The graph below shows the fees for in-home pet care.

![Graph of In-Home Pet Care Fees](graph_image_url) 

#### Graph Details:
- **Title:** In Home Pet Care Fees
- **X-Axis:** Hours (ranging from 0 to 8)
- **Y-Axis:** Fee (in dollars, ranging from 0 to 22, increasing by 2-dollar increments)
- The graph depicts an upward linear trend, indicating a constant rate of increase in fees with respect to hours.

### Question:
Which statement best describes the slope of the graph?

- The in-home pet care fee is $2.25 per hour.
- **(Selected)** The in-home pet care fee is $2.50 per hour.
- The in-home pet care fee is $4.00 per hour.
- The in-home pet care fee is $6.00 per hour.

#### Explanation:
The slope of the graph represents the rate of increase in fees with respect to the number of hours. To determine the slope:
1. Identify two points on the line. For instance, (0, 0) and (8, 20).
2. Use the slope formula: 

\[ \text{slope} = \frac{{\text{Change in fee}}}{{\text{Change in hours}}} = \frac{(20 - 0)}{(8 - 0)} = \frac{20}{8} = 2.50 \]

Thus, the rate of increase in fees is $2.50 per hour, hence the selected answer is correct.
