Key learning points

1. Multiple linear inequalities in two variables can be graphed on the same axes
2. By testing points in the various equations, you can determine the region that satisfies all the inequalities
3. This region is the solution set

Keywords

• Inequality - An inequality is used to show that one expression may not be equal to another.

• Region - A region is an area that graphically represents the solutions to one or more inequalities. Every coordinate pair within the region satisfies the inequalities that define the region.
