This lesson introduces the general form of all straight line graphs (y=mx+c), explaining the key features.
PowerPoint Lesson
- Coordinate the starter to begin with (make sure audio is turned on, as sound is embedded in slides)
- Phase 1: generate coordinates from functions
- Phase 2: plot the coordinates on worksheets
- Extension: Generate and plot coordinates for two non-linear functions
KS3 Maths Curriculum Area
Number Reduce a given linear equation in two variables to the standard form y = mx + c; calculate and interpret gradients and intercepts of graphs of such linear equations numerically, graphically and algebraically
