Or if we decrease our volume, decrease that volume in the balloon, our pressure will begin to increase. If we continue to increase or decrease the volume, that pressure will begin to increase exponentially, right? And that's what this represents. Now instead, suppose that I graph volume over one over P. Well, how would that look? Well, if I grab the volume over one over P, whenever this guy increases, this guy increases by the same ratio amount. And that's because volume times pressure gives you a constant.
