The slope itself, it could be positive, but it'll be coming less and less and less positive. And so we're looking for a place where the slope is positive, but it's becoming less and less and less positive. If you look right over here, the slope is positive, but the slope is increasing. It's getting steeper and steeper and steeper as we go. And then all of a sudden, it starts getting less steep, less steep, less steep, less steep, all the way to when the slope gets back to zero. So if we want to select an interval, it would be this interval right over here. Our slope is positive.
