Learning goals: Teacher Facing Find the solution to a two-variable inequality by graphing a related two-variable equation and determining the correct region for the solution. Interpret, in context, points on the graphs of equations and in the solution region of inequalities in two variables. Write inequalities in two variables to represent the constraints in a situation and identify possible solutions by reasoning.
