Question

Trendy Time race carts charges $25 plus $1.50 per lap. Which best describes the relationship between the

total cost and the number of laps?

A linear and proportional relationship
B linear, non-proportional relationship
C non-linear relationship
D None of the above

Answer 1

This is a linear, non-proportional relationship.

It is linear because there is a constant slope, or rate of change.

It is not proportional because it does not go through the origin. The y-intercept would be the $25 starting fee.
