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? (1 point)

Question

• The parking fee rises by $7.33 with each additional hour.
• The parking fee rises by $10 with each additional hour.
• The parking fee rises by $6 with each additional hour.
• The parking fee rises by $8 with each additional hour.

Answer 1

The parking fee rises by $6 with each additional hour.

This is determined by calculating the slope of the graph using the formula: (change in y) / (change in x).

Change in y = 44 - 20 = 24 (change in fee)
Change in x = 6 - 2 = 4 (change in hours)

Therefore, the slope (rate of change in parking fee for each additional hour) is 24 / 4 = $6.
