Ch 9: Graphing Linear Functions & Equations

About This Chapter

These lessons were developed to boost your knowledge of the process of graphing linear functions and equations. Take a look at nonlinear and linear functions, translations and more.

Graphing Linear Functions & Equations - Chapter Summary

This chapter will guide you to a better understanding of linear function and equations. Get to know graphing techniques and learn to understand the inverse function. The interpretation of initial value and rate of change are also covered. The lessons focus on the following:

  • Asymptotes: vertical and horizontal
  • Graphing absolute values and doing transformations
  • Determination of a function's initial value
  • Use of graphing to solve a system of equations

These video lessons run 5-10 minutes each, so it can be easy to make daily progress on your study program. Log in from any location using your mobile device anytime you have a few minutes. Track your progress on your dashboard.

Horizontal and Vertical Asymptotes

1. Horizontal and Vertical Asymptotes

No matter how hard you try to get to them, asymptotes remain out of reach. Learn about these invisible lines on graphs that show you places your equations just can't go.

How to Graph an Absolute Value and Do Transformations

2. 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!

Understanding and Graphing the Inverse Function

3. Understanding and Graphing the Inverse Function

If you use a function to map a to b, is there a way to go back from b to a again? Learn how to find and graph inverse functions so that you can turn a into b and back into a.

Linear and Nonlinear Functions

4. Linear and Nonlinear Functions

After watching this video lesson, you'll be able to tell the differences between linear and nonlinear functions. You'll also be able to identify both types just by looking at graphs.

Determine the Initial Value of a Function

5. Determine the Initial Value of a Function

In this lesson, you will learn to determine the initial value of a function by studying functions in the form of word problems, graphs and linear equations.

Interpret Rate of Change and Initial Value

6. Interpret Rate of Change and Initial Value

In this lesson, you'll learn how to interpret the rate of change and initial value of a function. We'll also discuss applying these principles to word problems and in real-world situations.

How to Solve a System of Equations by Graphing

7. How to Solve a System of Equations by Graphing

Watch this video lesson to learn how you can solve a system of equations by graphing. Learn when you have a solution and when you don't. Also learn how easy the solution is to spot.
