A linear graph of parking fees in dollars based on hours parked has the points (2,20) and (6,44) .
How would you interpret the slope of the graph as the rate of change in the parking fee for each additional hour of parking?(
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 can be determined by finding the difference in the y-coordinates (change in fee) divided by the difference in the x-coordinates (change in hours).
Using the given points, the change in fee is 44-20 = 24 and the change in hours is 6-2 = 4.
So, the slope of the graph is 24/4 = 6.
Therefore, the rate of change in the parking fee for each additional hour of parking is $6. This means that for each additional hour parked, the parking fee increases by $6.
