Virtual Nerd: What Are Horizontal Lines?

When looking at the coordinate pairs for an horizontal line, all the y-values will be equal. Yes, the same, no matter what the x-value is. And the line will never cross the x-axis. Check out this tutorial video to see what that actually...

A line plot is an effective way to visualize data. Watch this video for an explanation of line plots along with examples. [4:44]

Lines that are parallel have a very special quality. This tutorial takes a look at parallel lines and how they are different from other types of lines. [4:06]

The angles formed by perpendicular lines will always be the same. Take a look at this tutorial to learn about perpendicular lines and see a special trick involving them. [5:22]

This video tutorial introduces skew lines which are two lines that do not intersect and are not parallel. [3:46]

A line graph is one of many ways we can visually represent data. Watch this tutorial for examples. [4:05]

All vertical lines have the same slope. Watch this tutorial to learn all about vertical lines including their slope and what the equation of a vertical line looks like. [4:30]

Two lines that cut across one another are called intersecting lines. Learn about them by watching this tutorial. [7:19]

Trying to write the equation for a horizontal line given an ordered pair? Just keep in mind that a horizontal line is all about the y value in the ordered pair. Plain and simple! Whatever the y value is in the ordered pair becomes the...

Graph a horizontal line that goes through a given point by first plotting that point on a coordinate plane. Then draw a straight line left and right that goes through the point, and you're done!
