Lesson: Solving Systems of Linear Inequalities Mathematics • 9th Grade

In this lesson, we will learn how to solve systems of linear inequalities by graphing them and identify the regions representing the solution.

Lesson Plan

Students will be able to

identify the regions on a graph that represent the solution to a system of inequalities,
sketch a graph to represent a system of linear inequalities in order to solve them,
identify the system of linear inequalities represented by a graph.
