Lesson Plan

Graph a linear inequality in two variables as a half-plane, the extension of a one-variable number-line graph: draw the boundary line solid or dashed, and shade the side a test point selects

Determine whether a point satisfies an inequality by substitution

Match a two-variable inequality to its graph

Decide which rows of a table satisfy an inequality, identify the inequality a table of solutions is consistent with, and derive an inequality from a table of boundary points

"Make connections between tabular, algebraic, and graphical representations of linear inequalities in one or two variables by deriving one from the other." "Given a linear inequality or system of linear inequalities, interpret a point in the xy-plane in terms of the solution set."
