In this book, students find the intersection point of two lines by looking at their graphs. They then learn that they can find the intersection point by using algebraic methods called substitution and elimination. They use these methods to solve a variety of scenarios that can be modeled by two variables and two equations. They also learn how to graph systems of linear inequalities. Near the end of the book, they analyze a variety of scenarios that involve linear systems, while also getting a preview of nonlinear systems, which is a topic they will learn more about in Algebra 2: Book 6. This book builds on Algebra 1: Book 2.
