Linear equations and their graphs uses linear equations and straight-line graphs to model and analyse the relationship between two variables. The scope of this program includes piecewise-linear and step graphs as well as the graphical representation of simultaneous linear equations to explore breakeven analysis.
This learning program is made up of the following 6 topics, broken down into 32 concepts.
