Green Bridge Learning Resource Nchekwa Maka Gradient Of Linear Graphs

Gbogbo ọrọ náà

The gradient of a line measures its steepness: how much it rises for each step across. It is one of the most useful numbers in mathematics because it captures a rate of change, and it is the key to writing the equation of a straight line.

In this lesson you will find the gradient of a straight line, and (at Extended) calculate it from the coordinates of two points using the rise-over-run formula.
