Welcome to Chapter 7: Linear Relationships. In this unit, students will master the language of the coordinate plane, moving from basic ordered pairs to complex linear functions. We will dive deep into calculating slope (m), identifying x and y-intercepts, and graphing equations in various forms. This chapter also explores the mathematical properties of parallel and perpendicular lines.
