Question

A family purchased a tree that was 4 ft tall. The tree will grow at an average rate of 1.5 ft. per
year.
Write an equation in slope intercept form that models the growth g) per year and the height
of tree

Answer 1

Step 1:

The equation in the slope intercept form is

y = mx + c

Step 2

Average rate is the slope m

m = 1.5 ft

Intercept c is the initial height

c = 4 ft

y is the height and x is the time in years.

Final answer

y = 1.5x + 4
