### Graphs: The Coordinate Plane

#### Lesson Objective

This lesson shows you the basic parts of the Coordinate plane.

#### Why Learn This?

This plane is one of the most important idea behind graphs. A lot of mathematical ideas are created using this plane.

This also means that if you are taking up math, you definitely will come across it.

### Study Tips

#### Tip #1

These are the parts of the plane you should remember:

- Horizontal axis (also called x-axis)
- Vertical axis (also called y-axis)
- The point of Origin
- Quadrants

So, where are these parts located in the plane? Watch the video below to find out.

Before I begin, it good to know that, this plane was developed by this French mathematician a long time ago.

Now, let's take a look. This number line is the x-axis. Also known as horizontal axis.
The number line over here is the y-axis. Also known as vertical axis. Okay, now look at the center.

This point is called the point of origin. If you look carefully, the x-axis and y-axis divide the plane into 4 parts.

00:00:52.160

Each part is called a quadrant. Also, these parts are labeled, Quadrant 1, Quadrant 2, Quadrant 3 and Quadrant 4 respectively.

Okay, that is all for now. We will go through on how to use this plane in the next lesson.
