Reading straight lines

Coordinate grid with two parallel lines of gradient 2 and a perpendicular line of gradient minus one half, with a right angle marked

Most straight-line questions become easier when the equation is written as y=mx+cy = mx + cy=mx+c. Here, mmm is the gradient, which tells you how steep the line is, and ccc is the yyy-intercept, so the line crosses the yyy-axis at (0,c)(0, c)(0,c).

Step-by-step lessons covering Oxford AQA IGCSE Maths Parallel and Perpendicular Lines 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.
