The start of the lesson involves recognising the properties of linear functions both algebraically and graphically by identifying the gradient and intercept values.The development phase builds on this by teaching how to solve a pair of equations simultaneously using graphical methods.  As learning progresses students are challenged to solve equations in the form ax + by + c = 0.

Differentiated Learning Objectives

• All students should be able to plot a linear function using two points.
• Most students should be able to solve a pair of simultaneous equations with integer solutions graphically.
• Some students should be able to generate and solve a pair of simultaneous equations graphically.
