Linear Inequalities in Two Variables

Published on 11/28/2011

Activity Overview

Learn the basics of graphing linear inequalities.

Objectives

  • Discover the basics of graphing a linear inequality, e.g., the differences among the graphs of y > ax + b, yax + b, y < ax + b, and yax + b
  • Use a test point to check if the correct half plane is shaded
  • Sketch the graphs of linear inequalities and select a test point to verify the solution set
  • Students will use appropriate tools strategically (CCSS Mathematical Practice).

Vocabulary

  • Linear inequality
  • Half plane
