Summit Math Algebra 1 Book 6: Systems of Linear Equations and Inequalities - Paperback

by Alex Joujan (Author)

To help students succeed in learning math at school or at home, Summit Math books start with simple, foundational concepts and build on those ideas in small steps. Written by a math teacher with 16+ years of classroom experience, this series is designed to help students learn at different paces.

Each book is split into 2 parts: 1) Guided Discovery Scenarios, and 2) Homework and Extra Practice Scenarios. The Guided Discovery Scenarios gradually develop new concepts, building on previously learned topics. The Homework and Extra Practice Scenarios improve your understanding and increase your ability to retain what you have learned.

Each part has a separate Answer Key, which is included to promote learning. When you finish each scenario, you can check the Answer Key to see if you are ready to move on or if you need more guidance.

Book description:
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.
