The Equation for a Straight Line, y = mx + c

Updated: Jul 1, 2022

The formula y = mx + c represents a linear equation that plots a straight line on a graph. The y and x represent the axes, m the gradient and c the y-intercept (where the line crosses the y-axis).

Let’s look at a manipulation to find the equation for a straight-line using the following equation:
