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 change in the x-coordinates of any two points on a line in the xy-plane is called the "run." In the context of calculating the slope of the line, the run is used along with the change in the y-coordinates (called the "rise") to determine the steepness and direction of the line. The slope is calculated as the ratio of the rise to the run.
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!
They are coordinates that are plotted on the Cartesian 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 name of a point that is at (0,0) on a coordinate plane is called the origin.
The pair of numbers are called "coordinates".
The x coordinates are horizontal whereas the y coordinates are vertical on the Cartesian plane.
dots on a coordinate 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.
