What is a Vector?
Note:
When you're following directions, you not only need to know how far you're traveling but in what direction. Vectors are just like that! They have both a length and a direction! Follow along with this tutorial to learn about vectors and their parts. You can even see how to name a vector!

Ordered Pairs and The Coordinate Plane
-
What is the Origin?
The coordinate plane has two axes: the horizontal and vertical axes. These two axes intersect one another at a point called the origin. Learn about the ordered pair that indicates the origin and its location in the coordinate plane by watching this tutorial!
-
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.
