Problem 123. Tell me the slope

Although it is fairly easy to guess what you mean, your problem statement is not descriptive enough. Specifically, it is not clear whether the input is a single vector with both the rise and run, or if there should be two inputs. And what should the ordering be?

I'm not able to guess what "horizontal run" and "vertical rise" is. Where does the "next" belong to, to "vertical rise" or to "as a vector"?

a poor description for an uninspiring problem
