Course: Math 1
Description: 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.
Learning Targets:
1. Understand that all points on a half-plane are solutions to a linear inequality.
2. Determine whether the boundary line should be included as part of the solution set.
3. Graph the solutions to a linear inequality in two variables as a half-plane, excluding the boundary for noninclusive inequalities
4. Understand that the solutions to a system of inequalities in two-variables are the points that lie in the
intersection of the corresponding half-planes
5. Graph the solution set to a system of linear inequalities in two variables as the intersection of their
corresponding half-planes
