#### How Do You Name a Set That's Graphed on a Number Line?

If you have ever stared at a number line with dots on it and wondered 'How could I summarize these dots?', then this is the tutorial for you!

#### How Do You Graph a Set on a Number Line?

Number lines are great ways to represent a group of numbers, and in this tutorial you'll see how to graph a group of numbers on a number line

#### How Do You Plot Points in the Coordinate Plane?

Knowing how to plot ordered pairs is an essential part of graphing functions. In this tutorial, you'll see how to take an ordered pair and plot it on the coordinate plane. Take a look!

#### What is an Ordered Pair?

Ordered pairs are a fundamental part of graphing. Ordered pairs make up functions on a graph, and very often, you need to plot ordered pairs in order to see what the graph of a function looks like. This tutorial will introduce you to ordered pairs!

#### What is the Coordinate Plane?

You can't graph a function or plot ordered pairs without a coordinate plane! Learn about the coordinate plane by watching this tutorial.

#### What are Quadrants in the Coordinate Plane?

Did you know that there are four quadrants that help make up the coordinate plane? Learn about these quadrants, and what ordered pairs are located in each, by watching this tutorial!

#### How Do You Graph Ordered Pairs in Each Quadrant?

Plotting points on the coordinate plane is the foundation for graphing equations! Check out this tutorial to get some practice plotting points and identifying which quadrant each point is in.

#### What is the Opposite, or Additive Inverse, of a Number?

Have you ever combined two numbers together and found their sum to be zero? When that happens, those numbers are called additive inverses of each other! In this tutorial, you'll learn the definition for additive inverse and see examples of how to find the additive inverse of a given value.

#### What are Positive and Negative Numbers?

Positive and negative numbers (and zero!) are the building blocks of math. This tutorial will introduce you to positive and negative numbers and show you their location on a number line. Plus, learn a special thing about the number zero!

#### What is the Number Line?

A number line is a way we can visually represent numbers. This tutorial gives you a great introduction to the number line and shows you how to graph numbers on the number line in order to compare them. Check it out!
