Answer:

the rate is equal to
3.2(inches)/(week)

Explanation:

we have


h-15=3.2t

where

h is the height of a plant

t is the number of weeks after planting

so

Find the rate at which the plant's height is increasing

we know that

The given formula is a linear equation

The rate is equal to the slope of the linear equation

Isolate the variable h


h=3.2t+15

the slope is equal to
m=3.2(inches)/(week)

therefore

the rate is equal to
3.2(inches)/(week)
