Modeling
Applying methods of solving systems of equations and inequalities to real- world situations including problems with no solution and infinitely many solutions.
Mapped to CCSS Section# HSA.REI.C.6, HSA.REI.D.12
Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables. 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.
