Organize your data and find the rate of change.

LuckyWell [14K]

A .E is 7 inches for the left arm
E is 8 1/2 inches for the left foot
the inputs look like the length of the arm (ie x) the outputs are the length of the foot
rate of change=change in y change in x use the data you gathered or this equation they give you = 0.860 • + 3.302

B. find the difference in y, then the difference in x, then divide (y over x) to get the slope
8-7/7 1/2-6 1/2 = 1/1 =1

C.you plug in any (x,y) point you used to find the slope
Solve for B
y = mx+b y = 1*x + b 7.5 = 1*8 + b b =
7.5 - 8 = -0.5
y = x - 0.5

Hope this helps
