In other words, when does time go on the x-axis and when does time go on the y-axis? I heard that time is usually the independent variable, but are there exceptions to this rule? When would it be the other way around?When graphing, is time the independent variable or the dependent variable?

Time is generally the independent variable hence goes on the x-axis. Considering a speed-time or distance-time graph time goes on the x-axis. However, I have seen instances where time went on the y-axis i.e. it was the dependent variable. During one of my Bio practicals, we were investigating the effect of pH on enzymatic activity. We had to find out the time taken for a protein film to disappear, for certain pH values. Hence pH here was independent and time dependent.

We usually choose a dependent variable that is in some way controlled by the independent variable. Since time (unfortunately) answers to nothing and no one, there are rarely situations that would call for it to be the dependent variable. But I can think of a few.

Suppose we are roasting a turkey. How long should it be left in the oven? That depends on how much it weighs. It would be possible to construct a graph in which roasting time is a function of weight.

Now suppose you are staying at a resort. You like it, but how long can you stay? That depends on how much money you have.When graphing, is time the independent variable or the dependent variable?

most likely x-axis. its independent because time doesnt change with some characteristic, it is constant. however some other value may change over the course of time.When graphing, is time the independent variable or the dependent variable?

Depends on what you are graphing. If it is velocity, time is on the x axis.
