You can put this solution on YOUR website! Graph y=5x-2 how do I even start this?
----You need two points to graph a line.
If x = 0, y = 5*0-2 = -2, giving you point (0,-2)
--------------
If x = 2, y = 5*2-2 = 8, giving you point (2,8)
-----------------
Plot those two points and draw a line thru them to get:

You can put this solution on YOUR website! well, without a graphing program just do it the old fashioned way.
:
pick a value for x or y and solve for the other variable
:
make a table and then plot the points
:
for instance when x=1--->y=5(1)-2=3
:
so we have one point(1,3)....keep doing that for 3 or 4 points to make sure they really are lining up on the same line. here is the graph
