In this lesson, we will revisit equations for linear graphs and coordinates and investigate the relationship between solving simultaneous equations, and their appearance when plotted.

In this lesson, we will learn to identify points of intersection from linear equations as a precursor to solving simultaneous equations graphically.

In this lesson, we will learn how to solve simultaneous equations graphically by plotting them and identifying their point of intersection.

In this lesson, we will learn to recognise simultaneous equations with no solutions by representing the equations on a graph.

In this lesson, we will learn about the benefits of using graphical or algebraic methods to solve simultaneous equations.

In this lesson, we will learn how to represent inequalities on a graph and what coordinates will satisfy these inequalities.

In this lesson, we will learn how to shade regions between plotted lines to satisfy a set of inequalities.

In this lesson, we will learn how to solve more complex inequalities graphically, linking multiple straight-line graphs.
