2.41 Harder Non-Linear Simultaneous Equations Graphically Higher IGCSE PowerPoint Lesson

This 22-slide lesson focuses on solving harder simultaneous equations graphically that require plotting a straight line equation to find the points of intersection with quadratic and cubic graphs. Pupils are given a curve and need to use algebraic manipulation to “draw a suitable straight line”  as seen in IGCSE style questions. Printable sheets are included at the end that coincide with the examples and task. Students should already be familiar with solving non-linear simultaneous equations graphically before attempting this lesson.
