a linear graph of parking fees in dollars based on hours parked has 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?
To calculate the slope of the graph, we can use the formula:
Slope = (change in y)/(change in x) = (44-20)/(6-2) = 24/4 = 6
Therefore, the slope of the graph is 6. This means that for each additional hour of parking, the parking fee increases by $6. So, the rate of change in the parking fee for each additional hour of parking is $6.
