Standards

Common Core

• HSA.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.

TEKS

• A.3(H) – graph the solution set of systems of two linear inequalities in two variables on the coordinate plane
