Question

A linear graph of parking fees in dollars based on hours parked has the points left parenthesis 2 comma 20 right parenthesis and left parenthesis 6 comma 44 right parenthesis. How would you interpret the slope of the graph as the rate of change in the parking fee for each additional hour of parking?

Answer 1

The slope of the graph represents the rate of change in the parking fee for each additional hour of parking. In this case, the slope of the graph is (44 - 20) / (6 - 2) = 24 / 4 = 6.

Therefore, the rate of change in the parking fee for each additional hour of parking is $6. This means that for every additional hour of parking, the parking fee increases by $6.
