The horizontal coordiante (the x- coord) is the abscissa, and
the vertical coordiante (the y- coord) is the ordinate.
They are coordinates that are plotted on the Cartesian plane.
Why are two numbers necessary to locate points on a coordinate plane?
You do not have 3 coordinates in the Cartesian plane. The Cartesian plane is a plane and is therefore 2 dimensional. In 2 dimensional space you require only 2 coordinates. 3 coordinates are required to locate a point in 3-dimensional space but then it cannot be a Cartesian PLANE.
The x coordinates are horizontal whereas the y coordinates are vertical on the Cartesian plane.

Ordered pairThe coordinates! Guess how come the plane got to be called the coordinate plane!

See http://en.wikipedia.org/wiki/Complex_numberIn the complex number plane, it would be called the Origin, which has coordinates of (0, 0i)

The ORIGIN . #NB THe coordinates are writeen as (0,0) . NOT 00. Note the use of brackets and the commas.
The pair of numbers are called "coordinates".
The x coordinates are horizontal whereas the y coordinates are vertical on the Cartesian plane.

It will be located by the x and y coordinates on a flat plane such as the Cartesian plane.
The two points are the ordered pair of the coordinates of the point.
