Question 121441
y=3x-3 
---------
If you are asked to graph the equation you need to plot 
at least two points and draw a line thru them, as follows:
If x = 0, y=3*0-3=-3
If x = 1, y=3*1-3= 0
If x = 2, y=3*2-3= 3
-------------------------
Plot the points: (0,-3), (1,0), (2,3)
Draw a line thru them.
