Inequalities
IGCSE 0580
Topic: Algebra and Graphs
Core: C2.6
Represent and interpret inequalities, including on a number line.
Extended: E2.6
Represent and interpret inequalities, including on a number line.
Construct, solve and interpret linear inequalities.
Represent and interpret linear inequalities in two variables graphically.
List inequalities that define a given region.
Note: Shading should be used to represent unwanted regions (unless otherwise directed in the question).
Inequalities on a number line
In this video we will look at how to represent and interpret inequalities, including on a number line.
Solve linear inequalities
In this video we will rearrange inequalities - very similar to normal equations, but you need to "flip" the inequality sign when you multiply or divide by a negative number.

Regions in a Plane
IGCSE Exam example.

Regions in a Plane
IGCSE Exam example that is a little different. In stead of them giving the inequalities, they give you the shaded regions and then you have to give the inequalities.
