What is a gradient and an intercept?
This post will help you understand what a gradient and intercept are in Prelim Standard Math. The gradient of a line is the slope or steepness of a line, which is calculated by dividing the vertical rise by the horizontal run. Gradients can be either positive (goes up towards the right) or negative (goes down to the right).
An intercept of a line is where the line cuts the axis. The most common is the y-intercept.
