Chris has a miniature model of the boat that he is building. The length of the model is 4.5 inches and the height is 2 inches. If the length of the actual boat is 18 feet, what is the height?

A. 36 feet
B. 8 feet
C. 9 feet
D. 18 feet

B. 8 Feet

Step-by-step explanation:

You divide 18 feet, the actual length, by 4.5 inches, the modelled length, and multiply that by that modelled height.

18 / 4.5 = 4

4 • 2 = 8

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
