Activity Overview

In this activity, students will graph one linear inequality and then graph a system of linear inequalities as they apply to an area of land. Students will practice graphing systems of inequalities and determining if a points lies in the solution. In the extension, students are challenged to write a system of inequalities that describe the area of Mississippi.

Key Steps

  • Image

    Students are given a system of inequalities that represent a fenced-in yard. They will be able to graph all of the inequalities except x ≥ 0. Explain to students that this inequality would shade everything to the right of the y-axis. When entering the other inequalities students can type >= or <=, or they can insert ≥ and ≤ using the Symbol menu.
