From the graph, July's wait time is 44 minutes, October's is 53 minutes. The time period between July and October is \( 10 - 7 = 3 \) months.

Step2: Calculate rate of change

Rate of change formula is \( \frac{\text{Change in } y}{\text{Change in } x} \). Change in wait time: \( 53 - 44 = 9 \) minutes. Change in months: 3. So rate is \( \frac{9}{3} = 3 \).
