Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A rat weighs 3.5 pounds and costs $4.50 per week to feed, while a Beagle weighs 30 pounds and costs $9.20 per week to feed.

The slope is   $0.1774 / pounds

Step-by-step explanation:

From the question we are told that

   The weight of the rat is

     The cost of feeding the rat per week is $4.50

     The weight of a Beagle is  

     The cost of feed a Beagle per week is  $9.20

Now the slope can be evaluated mathematically as

substituting values

            $0.1774 / pounds
