The x-axis
Horizontal axis.
The combination of a horizontal axis and a vertical axis is called a Cartesian coordinate system, or in short, a graph.
It is the abscissa.
The word abscissa can either refer the horizontal axis (the x-axis) in a cartesian coordinate system or the actual coordinate plotted on the horizontal axis.
It was invented by rene desCARTES and therefore named after him. It was named after him from his latin name, Renatus Cartesius.

The Cartesian Coordinate System was discovered by Rene Descartes.
They are the coordinates.

Possibly because the first time that pupils are introduced to the name and concept it is has only two dimensions. These are usually represented as horizontal (x) and vertical (y) coordinates. Actually, many children meet the concept - in its 1-dimensional form - as the number line. It is not called a Cartesian coordinate system then, and they make only simple use of it. The Cartesian coordinate system is normally extended to 3-dimensional space in high school coordinate geometry when it is obviously not called a plane, and to multi-dimensional hyperspaces in advanced mathematics or physics.
