TExES Core Subjects EC-6: Linear Equations - Chapter Summary

Catch up on everything you need to remember about linear equations as you look through this helpful chapter. In each lesson, learn the terms, graphing techniques, and procedures for solving these equations. As you get set up to take the TExES Core Subjects EC-6 test, use this chapter to help you remember the following topics:

  • The definition of a linear equation
  • Writing linear equations in standard form
  • Graphing the intercepts of linear equations
  • Zero slope, undefined slope, and other related graphs
  • Graphing linear equations that use perpendicular and parallel lines
  • Steps for writing linear equations
  • The characteristics of a system of equations

Many of our lessons include videos, which can be viewed on your favorite device that connects to the Internet. In these videos, instructors discuss the topic of each lesson. Informative graphics and amusing animations bring the topics to life, which makes reviewing for the TExES Core Subjects EC-6 test a far more enjoyable process.

Even our text-based lessons are user-friendly. For starters, we use headers to separate the different topics within each lesson. By doing so, it makes it easier for your eyes to read and navigate the materials. Keywords are also set off in bold lettering, so you know which terms you will need to remember. Some of our keywords are hyperlinked to other lessons. You don't have to click on the hyperlinks, but having a bit more background information can prove useful.

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.

Linear Equations: Intercepts, Standard Form and Graphing

2. 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.

Graphing Undefined Slope, Zero Slope and More

3. 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!

Graphs of Parallel and Perpendicular Lines in Linear Equations

4. 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.

How to Write a Linear Equation

5. 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.

What is a System of Equations?

6. 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.
