#### How Do You Put an Equation in Standard Form Into Slope-Intercept or Point-Slope Form?

Looking for some practice converting the equation of a line into different forms? Then this tutorial was made for you! Follow along as this tutorial shows you how to take a linear equation from standard form and convert it into slope-intercept form and point-slope form.

#### How Do You Write an Equation for a Vertical Line?

Trying to find the equation of a vertical line that goes through a given point? Remember that vertical lines only have an 'x' value and no 'y' value. Follow along with this tutorial as you see how use the information given to write the equation of a vertical line.

#### How Do You Write an Equation for a Horizontal Line?

Trying to find the equation of a horizontal line that goes through a given point? Remember that vertical lines only have a 'y' value and no 'x' value. Follow along with this tutorial as you see how use the information given to write the equation of a horizontal line.

#### How Do You Graph a Line If You're Given the Slope and the Intercept?

Trying to graph a line from a given slope and y-intercept? Think you need to find an equation first? Think again! In this tutorial, see how to use that given slope and y-intercept to graph the line.

#### What Are Vertical Lines?

You may be able to guess that vertical lines are lines that go straight up and down, but did you know that all vertical lines have the same slope? In this tutorial, learn all about vertical lines including their slope and what the equation of a vertical line looks like!

#### What Are Horizontal Lines?

Ever look at the horizon when the sun is rising or setting? Know why it's called the horizon? It's a horizontal line! And just like the horizon, horizontal lines go straight left and right. In this tutorial, you'll learn all about horizontal lines including their slope and what the equation of a horizontal line looks like.

#### What's Slope-Intercept Form of a Linear Equation?

When you're learning about linear equations, you're bound to run into the point-slope form of a line. This form is quite useful in creating an equation of a line if you're given the slope and a point on the line. Watch this tutorial, and learn about the point-slope form of a line!

#### How Do You Write the Equation of a Line in Slope-Intercept Form If You Have a Graph?

Working with the graph of a line? Trying to find the equation for that graph? Just pick two points on the line and use them to find the equation. This tutorial shows you how to take two points on the graph of a line and use them to find the slope-intercept form of the line!
