Linear functions and graphs

Two PowerPoint lessons on straight line graphs, covering all aspects of GCSE Foundation, then Higher Tier mathematics:
plot graphs of equations that correspond to straight-line graphs in the coordinate plane;
use the form y = mx + c to identify parallel and perpendicular lines;
find the equation of the line through two given points or through one point with a given gradient
identify and interpret gradients and intercepts of linear functions graphically and algebraically

Clear presentations with lots of opportunities for learner engagement, and great for use on Zoom or other distance learning opportunities. Can be used simultaneously with learners in a classroom and at home.
