Step-by-step explanation:

The average rate of change refers to the relation between these variables.

Specifically, this problem can be modeled by a linear function, where the slope is the average rate of change.

So, such rate can be defined as

Where is the first pair and is the second one.

In this case, the first pair is and the second pair is . Replacing these coordinates, we have

Which is expressed in Fahrenheit.

Therefore, the average rate of change is 5.2 °F.
