what equation would represent the same linear relationship for the points (40,80) (80,115) (120,140) (160,165)
tiny-mole [99]
You can use the formula y1-y2=m(x1-x2)

to find m, you just do (y2-y1)/(x2-x1) so....

(115-80)/(80-40)= 35/40= 7/8

then plug it into the point slope equation:

y-115=7/8(x-80)

y-115=7/8x-70
y= 7/8 x + 45
