Final answer:
Independent and dependent variables are put on different axes of a graph to show their relationship. The independent variable is put on the x-axis while the dependent variable is put on the y-axis. This visually represents how changes in the independent variable (input) affect the dependent variable (output).
Step-by-step explanation:
Dependent and independent variables are put on different axes of a graph to visually represent their relationship and determine how changes in the independent variable affect the dependent variable. Typically, the independent variable is placed on the x-axis (horizontal axis) because it's the cause or input - it stands alone and isn’t affected by other variables you are attempting to measure. The dependent variable is placed on the y-axis (vertical axis) as it depends on the independent variable - it's the effect or outcome you are measuring.
For example, imagine a graph depicting the relationship between time (independent variable) and your height (dependent variable). Time would be put on the x-axis, and height on the y-axis. As the amount of time passes (moving right along the x-axis), you can monitor the changes in your height (moving up the y-axis).
