Answer:
Explanation: For a graph of position vs. time. The slope is the rise over the run, where the rise is the displacement and the run is the time. thus,
Slope = vavg=ΔxΔt
Note: Slope of the tangent line for a particular point in time = the instantaneous velocity
For a graph of velocity vs. time. The slope is the rise over the run, where the rise is the change in velocity and the run is the time. thus,
Slope = aavg=ΔvΔt
