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 linear graph represents the rate of change in the parking fee for each additional hour of parking. In this case, the slope can be calculated as the change in the parking fee divided by the change in the number of hours:
Slope = (Fee change) / (Hours change)
Using the given points and applying the slope formula:
Slope = (44 - 20) / (6 - 2)
= 24 / 4
= 6
Therefore, the slope of the graph indicates that for each additional hour of parking, the parking fee increases by $6.
