The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).

Why is the dependent variable on the y-axis?

In graphing jargon, the independent variable is plotted on the x-axis and the dependent variable is plotted on the y-axis. ... In any data set, the dependent or Y-variable is the one whose value depends on or is affected by the value of the independent variable.

Which variable is placed on the y-axis?

Graphing Rules

The independent variable is plotted on the abscissa (also called the x-axis or horizontal axis), while the dependent variable is plotted on the ordinate (also called the y-axis or vertical axis). The dependent variable is the one whose value changes as a result of changes in the independent variable.
