The z axis in the vertical axis in the Cartesian Coordinate System.
The combination of a horizontal axis and a vertical axis is called a Cartesian coordinate system, or in short, a graph.
The y intercept
Horizontal axis.
The x-axis
It is f(x), y or the "output".

Horizontal axis.
The x-axis
The two number lines are referred to as axes, the plural of axis. Normally the Cartesian system has positive and negative numbers on an x-axis (horizontal line) and a y-axis (vertical line).
It is f(x), y or the "output".
There are two of them which are the y-axis and the x-axis.
It is the x axis and y is the vertical axis whereas both axes intersect each other at right angles at the point of origin which is (0, 0)
The y-coordinate is referred to as the "ordinate." In a two-dimensional Cartesian coordinate system, it represents the vertical position of a point relative to the horizontal axis (x-axis). The y-coordinate indicates how far up or down a point is located from the origin (0,0).
