# Ch 2: Linear Equations

Watch online math video lessons to learn about x- and y-intercepts, slopes, systems of equations and more. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these linear equations topics.

## Linear Equations

What is a linear equation? Do you know what slope is? How about slope-intercept form? Are you familiar with y-intercept? If you are baffled by these terms (or just slightly unsure of them), then you need to watch our video lessons that will straighten you out and teach you all about linear equations, including what all these terms mean. You'll even learn a few other terms to help you out when working with linear equations.

You need to know more than just the definition of a linear equation - you also need to know how to write one. Let our lessons help you out. Learn how to write a linear equation when you are given various information. Also, get familiar with the terms 'parallel' and 'perpendicular' as they relate to linear equations.

Still, there is more to know about linear equations, and we won't leave you hanging. Our lessons will cover how to graph a linear equation that is not in slope-intercept form. Also, find out how to do more abstract algebraic equations. Discover how to graph an undefined slope, zero slope and more.

Are you aching for more knowledge? You'll want to watch our lessons that cover system of equations. Find out what it is, how to graph it and how to use it. Find out how to change a story into an equation so you can solve it. Also, become familiar with terms that include intersection point and substitution method.

Go get started now! There's so much to learn. Thanks for watching!
