What is a Linear Equation?

1. 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.

How to Write a Linear Equation

2. How to Write a Linear Equation

Simply knowing how to take a linear equation and graph it is only half of the battle. You should also be able to come up with the equation if you're given the right information.

Linear Equations: Intercepts, Standard Form and Graphing

3. 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.

What is a System of Equations?

4. What is a System of Equations?

So what happens if we want to compare more than one equation? Welcome to a 'system' of equations! Learn what one is, how to solve them and when they come up in real life.

How Do I Use a System of Equations?

5. How Do I Use a System of Equations?

There are a few classic algebra word problems, such as the one about two trains traveling at different speeds. In this lesson, you'll learn how to take a word problem and convert it into the system of equations that will allow you to find the answer using either substitution or elimination.

Dependent Events in Math: Definition & Examples

6. Dependent Events in Math: Definition & Examples

In this lesson, we will review the definition of a dependent even in math and the concept and formula for conditional probability. We will also look at some examples to clarify your understanding of this concept.

Direct Variation: Definition, Formula & Examples

7. Direct Variation: Definition, Formula & Examples

What is the relationship between the distance a car travels when cruise control is activated and the amount of money you have in the bank when you save regularly? Both are examples of direct variation. Learn more about direct variation in this lesson.

Equidistant: Definition & Formula

8. Equidistant: Definition & Formula

This lesson will discuss the concepts of equidistant and midpoint. We will explore the midpoint formula and show some examples of relevance in the real world setting.

Introduction to Linear Algebra: Applications & Overview

9. Introduction to Linear Algebra: Applications & Overview

What is linear algebra, anyway, and why should we care? What can we do with it? Let's look at some examples of the kinds of problems that can be made easier by the use of linear algebra techniques.

Linear Combination: Definition & Examples

10. Linear Combination: Definition & Examples

Linear combination is a method that is used to solve a system of linear equations. This lesson outlines the three basic ways that linear combination can be used to solve problems.
