- Inequalities
- On a line
- The solutions for linear inequalities can be shown on a number line
- If a open circle is used, the inequality can't be equal to the number but is a coloured circle is used, it can be equal

- Moe than one
- The region that is not needed may also need to be shaded instead
- More than one inequality can be shown on a graph by drawing two lines and shading the region that is wanted

- Solving
- Linear inequalities are solved the same as an equation (doing the same thing on both sides)
- An inequality uses < and >. The sign < means less than, and > means more than
- Solutions to inqualities are ranges of number e.g. 2 < 5 is 3 and 4

- Graphical
- Linear inequalities can be shown on a graph, the region is shown with a shaded area of a straight line
- The first step in drawing the line is to replace the > with an equals sign and plot the line
- The region the inequality wants shaded can be checked by choosing a point on one side of the line and seeing if it fits the inequality

- On a line
