Ch 6: Chapter 6: Linear Equations and Their Graphs

About This Chapter

The Linear Equations and Their Graphs chapter of this Prentice Hall Algebra I Textbook Companion Course helps students learn the essential lessons associated with linear equations and their graphs. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Linear Equations and Their Graphs textbook chapter.

How It Works:

  • Identify the lessons in the Prentice Hall Linear Equations and Their Graphs chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the algebra topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The slope of a line
  • Zero slope and undefined slope
  • The definition of a linear equation
  • Linear, increasing, decreasing, positive and negative functions
  • Line graphs and scatterplots
  • Graphing linear equations
  • Point-slope formula
  • Linear equations with parallel and perpendicular lines
  • The relationship between scatterplots and correlation
  • Transformations of absolute value graphs

How to Find and Apply The Slope of a Line

1. How to Find and Apply The Slope of a Line

In this lesson, we'll discover all about the slopes of lines. We'll learn about different types of slopes and how to find the slopes of lines. We'll use two methods: the slope formula and the slope-intercept form.

Graphing Undefined Slope, Zero Slope and More

2. Graphing Undefined Slope, Zero Slope and More

There are two special cases when it comes to slopes on the xy plane: horizontal and vertical lines. Without any more information, these examples can be pretty confusing. But with a little instruction, they end up being some of the easiest lines to graph!

What is a Linear Equation?

3. What is a Linear Equation?

Most cars won't be able to run for more than 250,000 miles, so how much longer will your car live? Linear Equations are the most basic kind of algebraic function and can help you answer questions exactly like this. Learn about what they look like, how they come up in your life and why they are powerful tools.

Identify Where a Function is Linear, Increasing or Decreasing, Positive or Negative

4. Identify Where a Function is Linear, Increasing or Decreasing, Positive or Negative

Functions do all kinds of fun things. In this lesson, learn how to identify traits of functions such as linear or nonlinear, increasing or decreasing and positive or negative.

Scatterplots and Line Graphs: Definitions and Uses

5. Scatterplots and Line Graphs: Definitions and Uses

After watching this video, you will be able to understand scatter plots and line graphs. You will also be able to use them to tell people a story about what you see and observe. You will also be able to read them.

Linear Equations: Intercepts, Standard Form and Graphing

6. Linear Equations: Intercepts, Standard Form and Graphing

Do you know what to do if an equation doesn't look like y=mx+b?! If not, then this video is for you. Chances are the equation is in standard form, so we'll learn how to use standard form equations, how to graph them and why they can be helpful.

Equation of a Line Using Point-Slope Formula

7. Equation of a Line Using Point-Slope Formula

It's time for a road trip to Las Vegas, and after four hours of driving at 60 mph ... Are we there yet? Learn the point-slope form of the equation of a line to help answer this age-old question.

Graphs of Parallel and Perpendicular Lines in Linear Equations

8. Graphs of Parallel and Perpendicular Lines in Linear Equations

When we deal with linear equations, we sometimes come across equations that are parallel to each other or perpendicular to each other. You will see what they look like when graphed in this video lesson.

Scatterplot and Correlation: Definition, Example & Analysis

9. Scatterplot and Correlation: Definition, Example & Analysis

A scatterplot is used to graphically represent the relationship between two variables. Explore the relationship between scatterplots and correlations, the different types of correlations, how to interpret scatterplots, and more.

How to Graph an Absolute Value and Do Transformations

10. How to Graph an Absolute Value and Do Transformations

Absolute value graphs normally look like the letter 'V', but transformations can change that 'V' in a number of different ways. As well as teaching you how to graph absolute values, this video will focus on a specific group of transformations called translations. Learn all about what that means here!
