Chapter 7 focuses on the fundamental principles of algebra and graphing, specifically looking at how two variables relate to one another. Students will learn to create tables of values and use them to graph linear equations, while also mastering key concepts like finding the slope of a line and identifying intercepts. The curriculum also introduces geometric applications on the coordinate plane, such as calculating midpoints and distances between points. Additionally, students will investigate the properties of parallel and perpendicular lines, providing a strong foundation for future advanced algebra and geometry courses..
