Lesson Narrative
In this lesson, students take a closer look at whether points on the boundary lines of the system's solution region are included in the solutions. Analyzing graphs and communicating observations about them require attention to precision (MP6). Students also apply these insights to solve more-challenging contextual problems. This work involves making sense of the information needed to solve the problems (MP1).
- Analyze given information about a situation involving multiple constraints and determine what additional information is needed to solve problems.
- Given a system of inequalities and their graphs, explain (orally and in writing) how to tell if a pair of values is a solution to the system.
- Practice writing systems of inequalities in two variables and finding the solution sets by reasoning or by graphing.
- Let’s use systems of inequalities to solve some problems.
- I can explain how to tell if a point on the boundary of the graph of the solutions to a system of inequalities is a solution or not.
