To determine the dependent and independent variables for a graph, I would need a description of the graph or information about what it represents.
In general, the independent variable is the one that is manipulated or changed in an experiment (usually plotted on the x-axis), while the dependent variable is the one that is measured or observed in response to changes in the independent variable (usually plotted on the y-axis).
If you provide more context or describe the graph, I can help identify the dependent and independent variables.
