3.1.3 Solving Systems of Linear Inequalities Key Objectives • Graph systems of linear inequalities. • Write and solve systems of linear inequalities. • Classify figures created by solution regions. Key Terms • A system of linear inequalities is a set of two or more linear inequalities. Example 1 Graphing Systems of Inequalities
The solution to a system of linear inequalities is often an infinite set of points that can be represented graphically by shading. To graph a system of inequalities, graph each inequality in the system. The region where the shadings overlap is the solution region of the system.
