6.8 System of Inequalities

Standard(s):

  • A.REI.D.12: Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.


Essential Question:

  • In what ways can the problem be solved, and why should one method be chosen over another?


Learning Target:

  • I can determine if the line of a linear inequality should be solid or dashed.(Application)

  • I can determine which side of a line should be shaded.(Application)

  • I can graph the solution set of a linear inequality.(Synthesis)
