So if you we're to be given a graph with the slope, how do you find the average velocity from it?

Also, what is velocity at halftime?

Thanks!

Average velocity = total displacement/time elapsed

On a displacement/time graph, average velocity is graphed using a curve that connects data points. The average velocity is the slope of the straight line connecting the endpoints of the displacement curve.

On a displacement/time graph, constant velocity is repesented by a straight line. The slope of the line equals velocity.
On a velocity/time graph the area under the curve equals the change in dispacement.
