Linear Systems


Using Systems of Inequalities

The image is of three colored birdhouses standing in a row.

By popular demand, the community center in your town is offering two sections of classes on making bird houses. At least 30 students must sign up or the classes will be canceled. Section 2 needs to have no more than twice as many students as Section 1. How can inequalities be used to represent the number of students that need to register for each class? In this lesson, you will learn how to solve this problem and others using a systems of inequalities.


  • Solve a system of linear inequalities by graphing
  • Use systems of linear inequalities to model situations
