How does the slope and steepness of the graph indicates the speed

Expert Answer
1) Slope of any graph indicates how the y-axis variable is changing with respect to the x-axis variable.
2) When we plot a distance-time graph and take the slope, we learn how the distance is varying with time.
3) Now, from basic understanding of the concept of Physics we know that distance variation with time gives speed. Speed = distance/time.
4) Hence, slope indicates the speed.
5) Another way of understanding this is through mathematical approach. Slope = Δy/Δx. In the distance time graph, we get slope = Δx/Δt which is nothing but speed.
