What does the slope of a work-time graph represent?

Explanation

To determine what the slope of a work-time graph represents, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Graph**: A work-time graph plots work done (W) on the y-axis against time (t) on the x-axis.

2. **Identifying the Slope**: The slope of a graph is defined as the change in the y-axis variable divided by the change in the x-axis variable. In this case, the slope (m) can be expressed mathematically as:
\[
