The slope of a distance-time graph represents the object's velocity. Velocity is calculated as the change in distance divided by the change in time.
Given:
The formula for velocity (slope) is:
$ v = \frac{\Delta d}{\Delta t} $
Substitute the given values into the formula:
$ v = \frac{10 \text{ m}}{2 \text{ s}} $
$ v = 5 \text{ m/s} $
Therefore, the slope on the distance-time graph is 5 m/s.
