In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format. The slope is a value that indicates the rate at which the y value of a ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

When a relationship between two variables is defined by a curve it means that the gradient, or rate of change, is always varying. An average speed for a journey can be found from a distance-time graph ...
