Students learn how to plot and derive the equation of straight-line graphs in the form y = mx + c. Learning progresses on from this to find the equation of parallel and perpendicular lines in the form ax + by +c = 0.
This unit takes place in Term 3 of Year 9 and is followed by graphical functions.
In this lesson, we learn about the length and volume scale factor of 3D shapes and the relationship between them.
How to solve simultaneous equations using the substitution method.
