Graphing Linear Inequalities in Two Variables (Part 2)

Use this activity to:

• interpret points in the coordinate plane and decide if they are solutions to the inequality, given a two-variable inequality that represents a situation.

• find the solutions to a two-variable inequality by using the graph of a related two-variable equation.

• write inequalities to describe the constraints in a situation.

Solutions to Systems of Linear Inequalities in Two Variables

Use this activity to:

• write a system of inequalities to describe a situation, find the solution by graphing, and interpret points in the solution.

• know what is meant by "the solutions to a system of inequalities" and can describe the graphs that represent the solutions.

• ,find values that satisfy each constraint individually, and values that satisfy both constraints at once, when given descriptions and graphs that represent two different constraints.
