Graph a linear inequality in two variables using at least two coordinate pairs that are solutions.
Clarifications:

Essential Understandings

Concrete:

  • Identify the y-intercept (where the line crosses the y-axis, or x = 0).
  • Graph the linear inequality.
  • Understand that a linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.
  • Identify above and below the boundary line.
  • Locate coordinate pairs.
  • Identify or shade the half-plane that is a solution to the inequality.

    An example of identifying or shading a half-plane that is a solution to an inequality.
Representation:
  • Understand ordered pairs.
  • Understand coordinate planes.
  • Understand <, >, =.
  • Understand the following related vocabulary: boundary line and linear inequality.

Category: Access Points
Date Adopted or Revised: 07/14
Cluster: Represent and solve equations and inequalities graphically. (Algebra 1 - Major Cluster) (Algebra 2 - Major Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
