Students learn how to plot and calculate linear inequalities on a Cartesian axes. As learning progresses they are challenged to identify regions on a grid using sets.

The start of lesson reminds students about the gradient and intercept properties of linear functions. The plenary challenges students to identify and describe a set of inequalities around a specific region.

**Differentiated Learning Objectives**

- All students should be able to plot and describe an inequality in the form y = a, x = a.
- Most students should be able to plot a linear equality on Cartesian axes.
- Some students should be able to plot and describe linear inequalities on Cartesian axes.
