a. s = 3(11.5) - 24

s = 34.5 - 24

s = 10.5 ⇒ avg shoe size

b. The y intercept is - 24.........[ not sure what this means .... size "-24" ???]

c. The x intercept occurs when s = 0

0 = 3f - 24

24 = 3f

8 = f [ in the context of this problem....an 8 inch foot equates to a size "0" ]

d. The slope = 3 [in the context of the probelm.......each increase in a one inch foot length results in a shoe size increase of 3]
