Straight Lines

Clear, exam-focused notes on gradients, y = mx + c, parallel and perpendicular lines, midpoints and lengths, with fully worked examples.

A complete 22-page IGCSE guide to straight-line graphs. It covers finding the gradient from two points or a graph, and reading the gradient and y-intercept from y = mx + c (including rearranging first). It also covers horizontal and vertical lines, and sketching lines using either the gradient or the two intercepts. It then teaches how to find the equation of a line from a gradient and a point, from two points, or from a graph. Later sections cover parallel and perpendicular lines, the midpoint and length of a line segment (including finding unknown coordinates), and where two lines intersect. Every method comes with clear diagrams and step-by-step worked examples. It ends with a formula summary, a keyword guide and exam tips.
