IGCSE Extended Booklet 14 - Straight Line Graphs | Original 30-page PDF

My original 30-page teaching booklet, supplied as an unchanged PDF. Distance, midpoint, gradient, line equations, parallel and perpendicular lines and mixed review.

The original questions, numbering, diagrams and page layout are preserved. This historical edition contains teaching notes, practice questions and selected answers. It is not a complete worked-solutions pack. Use the linked lesson description to see which questions that particular recording covers.

A separate one-page clarification PDF is included. Pages 5 and 6 - Question 4(b) and (c): Keep the gradient as 4/3 rather than rounding it to 1.33 during the working. In part (b), the line is y = (4/3)x + 17/3. In part (c), the line is y = (4/3)x, with zero intercept. The small nonzero intercept in the original scan is a rounding artefact.

Lessons with Dr Taylan Çeltik connect topics through a spiral learning approach.
