You can put this solution on YOUR website! y=5X-2 I need to solve for X first than for Y, so I can plot at least 3 points on my graph.
----
Solve for "x":
y = 5x-2
5x = y+2
x = (y+2)/5
-------------
Solve for "y":
y = 5x-2
If x = 0,y = -2 giving you point (0,-2)
If x = 2, y = 5*2-2 ; y = 8 giving you point (2,8)
================================
Plot the two points and draw a line thru them.
 graph(400,300,-10,10,-10,10,5x-2)}}
================================
Cheers,
Stan H.

...
y=5X-2
x=0 y=-2 (0,-2)
y=0,x=2/5 (2/5,0)
x=1,y=3 (1,3)
