sam wants $40.00 the drive to town and he makes $40.00 per hour after getting to town. how do you graph y=40+40x
This is a line so you only need to know two points.
when x=0 y=40+40*0 = 40+0=40 so that is (0,40)
when x=1 y= 40+40*1=40+40=80 so (1,80) is another point
NOW just plot these 2 pointsand rule a line between them :)
