Coordinate Geometry Concepts & Practice Problems - Chapter Summary

The lessons in this chapter will aid you in learning to create and use graphs to chart various functions. You'll gain an understanding of how to represent geometrical concepts on the xy-coordinate plane. The engaging video lessons cover skills that include:

  • Identifying parts of a graph
  • Graphing basic functions
  • Graphing piecewise functions
  • Graphing inequalities
  • Graphing 1- and 2-variable inequalities
  • Solving and graphing absolute value inequalities
  • Graphing circles

The instructors will lead you through each skill in creating graphs. The fun lessons will enable you to become familiar with graphing several types of functions and inequalities. By completing the self-assessment quizzes that accompany each lesson, you'll gauge your knowledge while becoming familiar with the types of questions you could face on the test.

8 Lessons in Chapter 7: Coordinate Geometry Concepts & Practice Problems
What Are the Different Parts of a Graph?

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.

Graphing Basic Functions

2. Graphing Basic Functions

Graphs are just like maps - when you know the language! Review how locations have x and y coordinates similar to latitude and longitude, and how to plot points in the Cartesian plane.

How to Graph Piecewise Functions

3. How to Graph Piecewise Functions

Piecewise functions are specific functions that have more than one piece. There is a special trick to graphing these type of functions, which you will learn in this lesson.

Graphing Inequalities: Practice Problems

4. Graphing Inequalities: Practice Problems

If you're already pretty familiar with what inequalities are and just looking for a place to practice your skills, this is the place. This lesson covers topics like 1-variable, 2-variable, compound, and systems of inequalities.

How to Graph 1- and 2-Variable Inequalities

5. How to Graph 1- and 2-Variable Inequalities

So an inequality is just an equation with a less than or greater than symbol. But what is the difference between 1 and 2 variable inequalities? What does have a greater than or equal to symbol change? When do you use a number line instead of a coordinate plane? Get those answers here!

How to Solve and Graph an Absolute Value Inequality

6. How to Solve and Graph an Absolute Value Inequality

Taking two skills and combining them to make a more complicated problem is a classic tactic in mathematics. If you feel confident with absolute values and inequalities, see if you can tackle them with their powers combined here!

Solving and Graphing Absolute Value Inequalities: Practice Problems

7. Solving and Graphing Absolute Value Inequalities: Practice Problems

Solving and graphing absolute value inequalities brings a lot of different skills together in one place. The practice problems in this video will give you a good chance to see more examples of absolute value inequalities but will also test your general algebraic knowledge.

Graphing Circles: Identifying the Formula, Center and Radius

8. Graphing Circles: Identifying the Formula, Center and Radius

Discover how to graph circles by finding key information like the center and radius. Identify circles by simply looking at the formula, and vice versa.
