Answer: The height is increasing at a rate of 3.2 inches per week.

To find this, you should put the equation in slope-intercept form. This can be done by adding 15 to both sides of the equation.

You will get h = 3.2t + 15

The value in front of the t is the slope. In this case, it is inches per week.
