I am having trouble please help me!

This chart shows the height of a tomato plant in inches, h, at weeks of growth, w.

Weeks of growth, w 4 6 10
Inches of height, h 6 9 15

Determine whether h is directly proportional to w and if so, determine the constant of proportionality.

A No, h is not directly proportional to w.
B Yes, h is directly proportional to w and the constant of proportionality is 3
C Yes, h is directly proportional to w and the constant of proportionality is 2/3
D Yes, h is directly proportional to w and the constant of proportionality is 3/2

1 answer

h = 3/2 * w
