x

Reading gradient and intercept

Coordinate graph showing the line y = 2x + 3, the y-intercept at (0,3), a gradient triangle with rise 2 and run 1, and a parallel line y = 2x - 1

Straight lines are usually written as $y = m x + c$ . Here $m$ is the gradient and $c$ is the y-intercept, which is where the line crosses the y-axis.
