Why do we need to draw a graph?
What is meant when a curve or stright line cuts the x-axis?
When a curve or stright line cuts the x-axis, does that have a significance in real life?
What is meant when a curve or stright line cuts the y-axis?

to draw a graph a point on the graph with a known x and y coordinate and the gradient of the graph are required
when a curve or straight liene cuts the x axis it means that the value of y for that point of points is 0. In real life it could signify the begining of something such as time which is usually represented on the y axis
if the curve or streight line cuts the y axis this means that value of x for that point or those points is 0. this could signify that a value such as distance is zero for this particular times on a distance vs time graph.
based on this the y intercept and x-intercept are terms used to express the points at which the value of x is zero and the value of y is 0 respectively
Can the value of x and y be represented on either axis? for example does time always have to be on a specific axis or can it be on either?
When you plot points on a graph you need o connect them it is only then you would be able to visibly see the change in gradient, or notice any trends being exibited.
when a curve or line cuts the x axis that is an indication that the corresponding value on the that shows or indicates that there is a direct connection or relationship between the two variables whatever they may be. It shows that they have something in common.
A graph is needed to simplify the representation data. It helps people to see the data in a new way so as to make clear deductions.
When a curve or a straight line cuts the x-axis this means that the value at the y-axis is zero in mathematical terms also it means that there is only a value for x.
When a curve or a straight line cuts the x-axis in real life this could mean an object has one particular quantity but lacks the value of another. In other words, what i am trying to say is that a graph's main purpose is to compare two properities and hence if one object or variable lacks a particular property but has another this could explain how a graph cuts only the x-axis.
Jason501 I don't completely understand what you are trying to say
x or y intercept is where the graph cuts the y or x access
hellion has raised a good point how do you determine what goes on what axis?
When a curve or a straight line cuts the y-axis this means that the value of x is zero or that there are no vaules for x and that that y has a specific value.
The x - intercept is the values of x where the line or curve cuts the x-axis. The y - intercept is the same pattern as the x- intercept however the y-intercept cuts the y-axis and the values only correspond to y.
we need to draw a graph so that we can see trends and patterns so we can make predictions.
when a curve or straightline cuts the x-axis this means that the value for the y is zero
when a curve or straight line cuts the y-axis this means that the x value is zero
We need to draw graphs so that we see inclines and declines in data represented.
the y-intercept is any value that has its x value as zero. and the same can be for the x-intercept.
this is why in the formula y=mx + c , c is known as the y-intrecept. this is the point on a straight line where the line cuts the y-axis
When a straight line or curve cuts the x-axis,it means that the y value is zero
i fully agree with brianiac when they say that " When a straight line or curve cuts the x-axis,it means that the y value is zero
"
because when the line cuts the x axis that means that the ponit is only on the x axis and there is no y value so the point stays at 0
brainiac you said graf uses to show inclines or declines....but wat about a stand still ....or conatant...lik a distande/time graf when a car is at constant speed......
well hellion in response to your ques posted in you 4th comment i would say that it depends on the wording of the ques. for eg. if they ask u to plot a graph for time vs distance; time is represented on the y-axis and distance on the x-axsis. And if they were to ask u to plot a graph for distance vs time; time is rep. on the x-axis and dis. on the y-axis. I'm not sure i have the order exactly correct though.
hellion i think you need to revise your first comment i can't understand what your saying!!!
hellion i do not know how to comment on the question " how does that sign.. on real life?'" and i read your comment...plz explain more so on that ques for me and the others seeing that sum didnot ans that!!!
psychotic time is always on the x axis.....and distance would be on the y....ent? yea i am pretty sure off that
WE NEED TO DRAW GRAPS TO SHOW A RELATION BETWEEN TWO OR MORE THINGS
Blessed08 distance time graphs
distance being y-axis time being x-axis "if a car is at constant speed"
it will be a straight horizontal line ok
I think that graphs are drawn so that we can observe the areas where there are changes occuring as brainiac and as brainiac said to see inclines and declines.
hellion
I would like to correct u on the first statement that u have made in your first line on this blog.
You mentioned that "to draw a graph a point ON THE THE GRAPH..."
U see the words in Caps. is your error. Why would u draw a graph if u already have one?
blessed08
I would like to respond on the question u asked brainiac about a stand still or constant.
In a distance/time graph when a car is constant it means that there is no change in speed.
I would have to agree on brainiac's comment that when a straight line or curve cuts the x axis it means that the y value is 0
Therefore I would say that when a line or curve cuts the y axis the it means that the x value is 0.
Would someone answer my question? I am a little puzzled now.
How about when a line or curve cuts both x and y axis, what does this mean? Does this have a significance in life?
The y intercept is the point at which the curve or line intersects the line x=0 i.e the y axis.
From my knowledge in the equation (y=mx+c) where c is the the y intercept.
psychotic
When u were referring to hellion u surely did not have the order correctly. You should know though that 'time' is always represented on the x axis.
I think the x intercept is the point at which a line or curve intersects the line y=0 i.e the x axis.
hey jason what are you trying to say? I think u kinda puzzling people's mind
"When a curve or a straight line cuts the x-axis in real life this could mean an object has one particular quantity but lacks the value of another.

what i understand by a straight line cutting the x axis is the value will not alawys be equal to zero beacuse it can cut anyway along the x axis
and if the straight line cuts the y axis it would give many values also
HELLION
Remember if a curve cuts the x axis the values for the y axis will be equal to zero.
but however the values for the x axis will be two values.
picture it in your mind
Ms. FARIEL
Can u tellme if that statemant is right. Correct me if im wrong.
i agree with Crimson Crock. The graph of values is drawn and the points are connected to to study the nature of the function
to psychotic:
i was trying to say that when drawing a straight line graph you need a ppoint that the line passes through and the gradient of that line
We need to draw a graph to show the motion or the trent of something
When a curve or straight line cuts the x-axis this means that the point or value is exactly on the x-axis and does not share its position with any other point meaning that the y-axis point or value will always be 0 at that point.
if u draw a line through y=5, you can get x=1 when y=5 or x=-1 when y=5 however, when x=0, y will still be equal to 5. if u observe u will see that at this point the line is touching and directly passing through y axis in which the term "cuts the axis" is used. Thats how u get:
When a curve or straight line cuts the y-axis this means that the point or value likewise on this axis is exactly lying on in and does not share its position with any other point meaning that the y-axis point or value will always be 0 at that point.
A graph is drawn simply to show th e relationship between two variables. when a curve or a straight line cuts the x-axis it is said that it intercepts at that point, at this point the y value will be equal to 0.
A graph consists of two components: vertices and edges. Vertices are simply labels such as numbers and edges are the connections between the vertices.so inorder to draw a graph u need x and y coordinates
when a curve or stright line cuts the y-axis the coordinates of that pt will be (0,y value).yes
when a curve or stright line cuts the x-axis the coordinates of that pt will be (x value,0).yes
x-intercept (0, y term)
y-intercept (x term,0)
we ned a graph to fine the rate of change from given data
when a curve or straight line cuts the x axis it means that the value of y for that point of points is 0
when a curve or straight liene cuts the y axis it means that the value of x for that point of points is 0.
the sigificances of the y and x intercept, is that two points are need to obtain the rate of change
