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.

Equation of a Line

Step-by-step lessons covering Oxford AQA IGCSE Maths Equation of a Line for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
