Return a list containing one dictionary with that solution. Likewise, if there’s only a single solution, If thereĪre no solutions, return an empty list (rather than a list containingĪn empty dictionary). Return a list of dictionaries containing the solutions.

Topic C combines learning from topics A and B to explore and model with systems of equations and inequalities. Students are expected to use tools of checking solutions strategically as well as attending to precision in notation and graphing. Topic B expands students’ understanding of a single-variable inequality to linear inequalities. Students build on conceptual work from eighth grade on independence and dependence to define, create, and model with inverse functions.

Topic A builds on work from Unit 3 to expand the idea of a solution to a coordinate point and to review identifying features of linear functions as well as graphing and writing equations in different forms to reveal properties. Proficiency of algebraic manipulation and solving, graphing skills, and identification of features of functions are essential groundwork to build future concepts studied in Units 5, 6, 7, and 8. Students are introduced to inverse functions and formalize their understanding on linear systems of equations and inequalities to model and analyze contextual situations. In Unit 4, Linear Equations, Inequalities, and Systems, students become proficient at manipulating, identifying features, graphing, and modeling with two-variable linear equations and inequalities.
