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 <span>rate of change=<span>change in y change in x</span></span> 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 <span>y = x - 0.5</span>
