A.
An additional 3.87 years is associated with an additional foot of growth.

B.
An additional year is associated with an additional 3.87 feet of growth.

C.
An additional 1.29 years is associated with an additional foot of growth.

D.
An additional year is associated with an additional 1.29 feet of growth.

Answer 1

3,3.87),(6,7.74)

slope = (7.74 - 3.87) / (6 - 3) = 3.87 / 3 = 1.29

Explanation:

Answer 2

(3,3.87),(6,7.74)
slope = (7.74 - 3.87) / (6 - 3) = 3.87 / 3 = 1.29

An additional year is associated with an additional 1.29 feet of growth
