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 ...

Revise how to work out the gradient of a straight line in maths and what formula to use to calculate the value change in this Bitesize guide.

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient close gradientA measure of the slope of a line. The ...
