Would Time Be on the X or Y Axis?

Time is the independent variable and will always be placed on the x-axis. The lines on the graphs can tell you many different things. For example: The slope of a line (steepness) can tell you speed.

Is time always on x-axis?

The x-axis (horizontal) always shows the independent variable, that is the variable over which you have no control. This is most obvious when graphing distance and time. Time will always go on the x-axis, since it is independent of anything else.

Is time the X or Y variable?

For example, time is always an independent variable (and goes on the x-axis) because the experimenter is choosing which time points to take measurements at—1 second intervals, 5 minute intervals, etc.
