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.

Math Video Transcript

This video introduces you to the parts of the coordinate plane. It is important for you to remember these parts.

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.

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.
