I seriously had to look at it 18 times before I got it, and my last comment was not well-phrased.
So, the first chart is straight-up, jobs vs. time. The second chart is the first derivative - delta(jobs) vs. time. All good so far. But the text in red (67,600 and 6,400), that's actually the slope of the the line in the second graph, so, the second derivative, jobs/month^2.
(Did I say that right that time? I think I said that right that time.)
