Fitting Linear Models to Data · Review Exercise 76

Consider this scenario: The median home values in subdivisions Pima Central and East Valley (adjusted for inflation) are shown in the table. Assume that the house values are changing linearly.
$$\begin{array}{ccc}\text{Year}& \text{Pima Central}& \text{East Valley}\\ \text{1970}& \text{32,000}& \text{120,250}\\ \text{2010}& \text{85,000}& \text{150,000}\end{array}$$

In which subdivision have home values increased at a higher rate?

Its source prints no answer for this problem, so there's nothing to check against.
