Systems of equations and inequalities are used to model and analyze the quantitative relationships of real-world applications. In this unit, students study the relationships between two linear functions and develop an understanding of systems of linear equations and inequalities. These concepts provide a foundation for further study of systems of linear and non-linear functions in subsequent units and courses.
The purpose of this unit is to further students’ understanding of linear equations and inequalities by examining relationships between two linear equations or two linear inequalities. Students investigate connections among numeric, graphic, and algebraic representations of systems of linear equations. They investigate several methods to solve systems graphically, numerically, and algebraically. Students analyze the use of systems of linear equations in interpreting real-world applications and they create systems of equations and inequalities to solve real-world problems.
Unit 4 is typically a four-week unit taught in December and January.
