Gradient - GCSE Maths Definition

In GCSE Maths, the term 'gradient' refers to how steep a line is on a graph. It tells you how much the line goes up or down each time you move one unit across. To find the gradient, you look at how much the height (or y-value) changes when you move one step along the x-axis. Mathematically, it's figured out by dividing the change in the y-values by the change in the x-values between two points on the line. A positive gradient means the line slopes upwards, while a negative gradient means it slopes downwards. If the gradient is zero, the line is flat and horizontal.
