The dependent variable is the thing that changes. The blood pressure changes, right?
So, the caffeine level is the independent variable.
Along the x axis is: amount of caffeine ingested
Along the y axis is: height of blood pressure

The independent variable is the level of caffeine.
The dependent variable is blood pressure.
You manipulate the independent variable and observe changes in the dependent variable.
