The domain. The independent variable. The x values in a function or two variable equation.
Normally, the numbers on the horizontal axis represent the data you start with to figure out what will happen when you apply a function to those numbers. In a linear equation, y=3x+2 will cross the horizontal axis at (-2/3, 0), and will cross the vertical axis at (0,2), creating a line that moves upward to the right as the values on the horizontal axis increase.

The x-axis represent the horizontal line while the y-axis represents the vertical line.
if u mean math then its the x-axis if u want the vertical then its the y-axis
In the Argand diagram (complex plane), numbers on the horizontal axis represent real numbers.
For an example, if negative and positive directions on the X and Y axes represent left/right and forward/backward, Z axis represents up/down.
The y axis represents the vertical co-ordinates whereas the x axis represents the horizontal co-ordinates.
