Question 153930: I seem to have a problem understanding HOW to plot a graph. I'm willing to try but I'm visually oriented and need to see the graph in front of me so that I can work backwards in order to figure out what needs to be done. This is the graph I am trying to plot:
y = 5x - 2
Thank you.

You can put this solution on YOUR website! y = 5x - 2
------------
You make plots by finding a number of points and then connecting them.
In this case, it's linear, meaning it's a straight line plot, so 2 points is sufficient. You can find any 2 points. I'll find the points where it crosses the X and the Y axes.
Y intercept:
Set x = 0
y = 0 - 2
So the point is (0,-2)
X intercept:
Set y = 0
0 = 5x - 2
5x = 2
x = 2/5
So the point is (0.4,0)
Plot those 2 points and draw a straight line through them.
