Question 245521
How am i suppoesed to graph this eqation? 
y=-2x+8
---------------
It's a straight line, so 2 points are sufficient.
Pick numbers for x and find y.
x = 0, y = 8 --> (0,8)
x = -4,y = 0 --> (-4,0)
Plot the points and draw a line thru them.
I don't know another way.  
Well, actually I do, but this one works.
