Overview

Students solve linear absolute value equations in a single variable and use their graphing calculator to verify solutions.

Key Steps

  • Image

    In the first problem, students will solve absolute value linear inequalities and check the solutions using the Test menu on the graphing calculator.

  • Image

    In the second problem, students use the ABSINEQ program to graph absolute value linear inequalities and are introduced to writing compound inequalities.

  • Image

    In the third problem, students learn how to simplify absolute value inequalities before writing it as a compound inequality. They will verify their answers by graphing the inequality using the ABSINEQ program.
