Students build on Unit 3 content to create, interpret, and graph systems of equations and inequalities. Students will continue to describe how variables are related within a given situation, and will create two related function rules that each model a distinct relationship in the situation. Graphs, tables of values, and function rules are each used to determine the solution set of a system of equations or inequalities. Students will compare different solution methods to strategically choose which method best conveys a system’s solution set.

Essential Questions:

- How can we apply our knowledge to model real-world situations?
- How can we represent and analyze our solutions to problems?
- How can we represent the same thing in multiple different ways?
