Coordinates:

A point can be described by a number pair. Consider point A described
by a pair of numbers on the Cartesian plane as shown below.

cod

The first number i.e. 8 is the horizontal displacement of point A from
the origin O. This is known as the x–coordinates. The second number
i.e. 6 is the vertical displacement of point A from the origin. This is
known as the y–coordinate.
Pont A is located by moving 8 units along the x–axis and 6 units by
moving along the y–axis. Any point can be located in this way.
Example
Draw the Cartesian plane and locate the following points.
A (3, 2), B (2, -4), C (0, 3), D (5, 0), and E (-3, -1)
