• 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
