Straight Line Graphs | OCR GCSE Maths Higher | 40 Worked Examples (J560)

Straight line graphs for OCR GCSE (9-1) Mathematics Higher tier (J560). 40 exam-style questions with fully worked, mark-scheme-annotated solutions: reading gradient and y-intercept from an equation and from a graph, gradient between two points, rearranging into the form y = mx + c, the equation of a line through a point with a given gradient, the equation of a line through two points, parallel lines, perpendicular lines via the negative-reciprocal rule, midpoints, points of intersection, gradient as a rate of change on a distance-time graph, collinearity, perpendicular bisectors, and the equation of a tangent to a circle at a given point. Progressive Easy to Challenging difficulty. Every working line is annotated, with OCR M/A/B marks folded in on the real mark-scheme lines. Built for OCR’s no-formula-sheet exam: the gradient, y = mx + c and perpendicular-gradient facts must all be recalled from memory, so the pack opens with the key facts and a method-choice strategy. Perpendicular lines and tangent-to-a-circle work are flagged as Higher-only content. Calibrated against OCR J560 past papers and mark schemes, not ported from another board (no function notation, no P-mark). Ideal for revision, homework, and 1-1 tuition.
