To determine how much Vince is paid for one hour of work, we can analyze the line on the graph.

From the graph, we can see:
- At 20 hours, Vince earns $180.
- At 40 hours, Vince earns $360.

To find the rate of pay per hour, we can calculate the pay per hour based on the information given.

1. **Calculate the pay rate** using the hours worked and the total pay.
- At 20 hours:
\[
\text{Pay per hour} = \frac{\text{Total Pay}}{\text{Total Hours}} = \frac{180}{20} = 9.00
\]

2. **Confirm with the total at 40 hours**:
- At 40 hours:
\[
\text{Pay per hour} = \frac{360}{40} = 9.00
\]

Both calculations show that Vince's pay for one hour of work is $9.00.

Thus, the correct answer is:

**B. $9.00**
