Students learn how to plot linear graphs and use them to estimate the solutions to equations. As learning progresses students begin to plot and identify the properties of quadratic graphs. Later, they estimate the solution to quadratic equations using graphical methods.
This unit takes place in Term 3 of Year 8 and follows Expressions, Equations and Formulae.
