The y-axis should be labeled as time, which is the dependent variable. The y-axis should be labeled as distance, which is the independent variable. The x-axis should be labeled as distance, which is the dependent variable. The x-axis should be labeled as time, which is the independent variable.
I gave my students this multiple choice question: How should a line graph be used to display distance and time data for a moving object?

Only one answer is correct among these 4 choices:
- The y-axis should be labeled as time, which is the dependent variable.
- The y-axis should be labeled as distance, which is the independent variable.
- The x-axis should be labeled as distance, which is the dependent variable.
- The x-axis should be labeled as time, which is the independent variable.

Could you tell me which one is correct?

The x-axis should be labeled as time, which is the independent variable.
