About This Chapter
ELM Geometry: Graphing Basics
Get ready for the ELM math by watching these online video lessons, then test your knowledge using our interactive online quizzes. The video lessons in this chapter cover the following topics:
- Identifying different parts of a graph
- Identifying and plotting points on the number line
- Identifying and plotting points in the coordinate plane
The ELM is a math proficiency exam required for all incoming students to schools in the California State University system. You can learn more about the topics on the ELM.
The Graphing Basics chapter is one of many chapters in this course that is focused on Geometry-based skills. Geometry comprises approximately 30% of the entire ELM exam. Other chapters in this courses address other geometry-focused topics, including the following:
- Finding the perimeter, area and volume of various geometric figures
- Using and applying the Pythagorean Theorem
- Solving geometric problems the demonstrate an understanding of essential geometric figures
- Determine angles in the plane (using properties of intersecting lines, parallel lines and perpendicular lines)
- Graphing linear and quadratic functions
- Transferring features of an equation to features of a corresponding graph
Mastering the concepts covered in this chapter will provide you with a solid foundation for the corresponding portion of the ELM.
1. What Is a Number Line?
A number line is a visual representation of all real numbers. In this lesson, we'll learn how to identify points on a number line. We'll also practice addition and subtraction, letting the number line do all the hard work.
2. What Are the Different Parts of a Graph?
Being able to read a graph isn't just vital for an algebra class. Graphs and charts are used everywhere! We'll take a crash course on the basic x/y plane used in algebra and the fundamental vocab you need.
3. Plotting Points on the Coordinate Plane
If you'll be working with a graph, otherwise known as the coordinate plane, it's essential to understand how it works. This includes learning the parts of a graph, identifying points and plotting points.
