```Question 54302
Hi Sher,
If you're graphing a linear equation (I assume that's what you're doing because that's what they start you off with.)then you can plot a couple of points, or as many as your teacher feels is necessary and connect the dots.  I'll try to show you an example.
First, take a look at the rectangular cartesian graph. The horizontal line (the one going left to right) is the x-axis and  the vertical line (the one going up and down) is the y axis.  Going right of the origin gives positive x's, to the left is negative x's.  Going to up fromt the origin gives is positive y's going down gives negative y's.
{{{graph(300,200,-10,10,-10,10,25)}}}
If you needed to graph a point (x,y)=(2,3) You'd go right 2 on the x-axis and then from there 3 units up then put your point there.
For an example problem lets graph y=x+1.
You can pick any number you want for x, you want to pick one that is easy to fit on your graph.
Let x=(-1) Substitute -1 where x is in your equation and solve for y.
y=(-1)+1=0 Plot(-1,0)
Let x=0
y=0+1=1 Plot(0,1)
Let x=1
y=2+1=3 Plot (1,3)
Connect the dots and you have a line that looks like:
{{{graph(300,200,-10,10,-10,10,x+1)}}}
Hope that helps.
Happy Calculating!!! ```
