Gradient and line equations

Straight line on coordinate axes with y-intercept at (0,3) and a gradient triangle showing rise -4 and run 2

A straight line is described by how steep it is and where it crosses the yyy-axis. In the equation y=mx+cy = mx + cy=mx+c, mmm represents the gradient and ccc is the yyy-intercept.

Step-by-step lessons covering Edexcel AS Level Maths Straight Line Graphs for AS Level Maths. Each lesson breaks down 5.1 y = mx + c, 5.2 Equations of Straight Lines, 5.3 Parallel and Perpendicular Lines, 5.4 Length and Area, and 5.5 Modelling with Straight Lines, then works through exam-style questions in Paper 1 and Paper 2 format. Build fluency in the core algebra, surds and trigonometry topics early, since they underpin the calculus, statistics and mechanics content that follows.
