About This Chapter
Geometry: Graphing Basics - Chapter Summary
Some questions on the math portion of the CAHSEE ask you to be familiar with the four quadrants and x- and y-axes appearing on the coordinate plane. Get ready to successfully answer these questions by watching this chapter's video lessons, which are designed to show you how to do the following:
- Use number lines
- Identify parts of a graph
- Plot points on the coordinate plane
- Determine the areas and lengths of simple figures
Instructors teaching these short video lessons use plenty of illustrations to drive home key concepts and terminology. Take advantage of their experience and expertise to review geometry topics covered in your own course or get extra help with those areas you may be unfamiliar with. The lessons feature video tags and corresponding transcripts that allow you to skip ahead or go back to the material you're looking for. There are also practice problems included in the self-assessment quizzes attached to each lesson.
Geometry: Graphing Basics - Objectives
Content in this chapter can help you prepare for the CAHSEE math exam's Measurement and Geometry section, which includes 17 of the test's 80 multiple-choice questions. You may be asked to interpret graphs or plot a series of points to determine an image's shape, length and area. Some questions also ask you to apply these concepts to solve word problems. Your score on this part of the exam and others will be used to assess your math skills and determine your eligibility for a high school diploma in California.
1. 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.
2. 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.
3. How to Graph Reflections Across Axes, the Origin, and Line y=x
A graph can be reflected in three ways - across the axes, the origin and the line y = x. There are specific rules to perform each reflection. This lesson will describe those rules and show you how to perform these reflections.
4. Plotting Simple Figures on Coordinate Graphs
One of the most basic parts of geometry is learning how to plot simple figures onto a coordinate graph. In this lesson, we learn how to do that, as well as calculate the area and length of the figures we sketched.
