In a distance-time graph, speed/velocity is represented by the ...

Explanation:
Speed is the rate at which distance changes with time, so in a distance–time graph the slope of the line represents speed. A steeper line means a faster speed, and a flat (horizontal) line means no movement. If the line curves, the slope changes, giving the instantaneous speed at each point. The line itself isn’t speed or distance; what matters for speed is how quickly distance increases as time passes.
