So this is my W axis, this is my time axis. We're starting at 1,400 tons, and we are increasing from there. They're telling us that it is an increasing function. So maybe it looks something like that. And then our slope, our slope right over here, and I don't know, I haven't drawn W exactly that accurately. I'm just guessing what it might look like at this point. The tangent line has a slope of 44.
