The x-axis and y-axis separate the coordinate
plane into 4 parts.

Each line has a number associated with it.
Just like the dashes on a number line.

These points are described by ordered pairs.

An ordered pair is a set of parenthesis with two numbers inside. The numbers are separated by a comma.
( 1 , 3 )
![Page 13: This vertical line is called the y-axis. y This horizontal line is called the x-axis. y x](https://reader034.vdocument.in/reader034/viewer/2022042814/551afb505503465e7d8b5419/html5/thumbnails/13.jpg)
( 1 , 3 )
The first number is called the x- coordinate.
![Page 14: This vertical line is called the y-axis. y This horizontal line is called the x-axis. y x](https://reader034.vdocument.in/reader034/viewer/2022042814/551afb505503465e7d8b5419/html5/thumbnails/14.jpg)
( 1 , 3 )
The second number is called the y- coordinate.
![Page 15: This vertical line is called the y-axis. y This horizontal line is called the x-axis. y x](https://reader034.vdocument.in/reader034/viewer/2022042814/551afb505503465e7d8b5419/html5/thumbnails/15.jpg)

Now, let’s graph this ordered pair on the coordinate plane.
