Answer to Problem 75E
Explanation of Solution
Calculation:
The cost of driving
The cost of driving
The cost and distance are considered coordinates. The slope of the line is
So, the line joining the points is
Where
Hence, the linear equation that relates

Answer to Problem 75E
A linear fuction gives a suitable model because we would expect the cost of driving to be more or less proportional to the number of miles driven.
Explanation of Solution
Calculation:
A linear fuction gives a suitable model because we would expect the cost of driving to be more or less proportional to the number of miles driven.
Hence, a linear relationship is a suitable model for this situation.
