I believe you meant the "independent" variable, and it is the X axis. The Y axis (the vertical one) is for the dependent variable.
The 'Y' axis.
The independent variable is along the bottom or horizontal or x axis. The dependent variable is up the left hand side or vertical or y axis
It is a velocity-time graph in which time is plotted along the horizontal axis and the velocity of an object in a selected direction is plotted along the vertical axis.

The x-axis
Usually the x-axis of a bar graph shows a control range, and is plotted on the bottom of the graph. Time is a common x-axis example.
X-Axis goes from left to right on a graph.

With a line graph you use lines. You put numbers at the bottom of the graph and numbers on the side. In other words the bottom numbers are on the x axis and the numbers on the side are on the y axis. Then when you have the dots on the graph you connect them and then it makes a line.
