|Subject Area||Algebra 1 Honors|
|Unit of Instruction||Unit 5 – Systems of Linear Equations and Inequalities|
MAFS.912.A-REI.3.6: Solve systems of linear equations exactly and approximately (with graphs), focusing on pairs of linear equations in two variables.
MAFS.912.A-REI.4.12: Graph the solution set to a system of linear inequalities in two variables as the intersection of corresponding halfplanes.
|Learning Targets and Learning Criteria|
• explain why and identify when some linear systems have no solutions or infinitely many solutions. • identify systems whose solutions would be the same through examination of the coefficients. • solve a system of linear equations algebraically (by substitution or elimination) to find an exact solution. • graph a system of linear equations using appropriate axis labels and scale and determine the approximate solution by estimating the point of intersection. • explain the steps in an algebraic proof that shows one equation being replaced with another to find a solution for a system of equations. • explain why a method was chosen when solving a system of equation.
• define linear inequality, half-plane, and boundary. • graph a linear inequality of a coordinate plane, resulting in a boundary line (solid or dashed) and a shaded half-plane. • graph the solution set to a system of linear inequalities on a coordinate plane. • explain that the solutions set for a system of linear inequalities is the intersection of the shaded regions (half-planes) of both inequalities. • verify points in the intersection of the half-planes to check if they represent a solution to the system. solve problems involving a single linear inequality or systems of linear inequalities graphically.
