Ch 15: Geometric Graphing Basics

About This Chapter

Use these video lessons and self-assessment quizzes to help you learn the basics of graphing in geometry. The information from these lessons will help you prepare for the ELM math exam.

Geometric Graphing Basics - Chapter Summary

These video lessons will give you a solid foundation in geometric graphing in preparation for the ELM math test. You'll learn how to identify points on a number line, as well as how to use the number line to help you add and subtract. Other lessons cover the basics of reading a graph, or coordinate plain, and how to plot points on it. You will also learn about the vocabulary used when working with graphs. Topics included in this chapter and in questions on the ELM include:

  • Identifying and plotting points on a number line
  • Identifying parts of a graph
  • Identifying and plotting points on a coordinate plain

Experienced instructions will guide you through these lessons, explaining each point as you go. You can check your knowledge through the self-assessment quizzes that follow each lesson and go back and rewatch the video as many times as you wish.

Geometric Graphing Basics Chapter Objectives

Many first-time students at California State University are required to take the ELM to determine their placement in a mathematics class. The ELM consists of 50 multiple-choice questions, and you will have 90 minutes to complete it. It is divided into three sections, and the material covered in this chapter is found in the Geometry section, which makes up approximately 30% of the entire test. Questions from this chapter found on the ELM may include:

  • Using a number line
  • Identifying parts of a graph
  • Identifying and plotting points on a coordinate plain
