**David Q/R**, Tuesday, January 1, 2013 at 4:14pmThe distance between the X coordinates is 2 minus -5 = 7. The distance between the Y coordinates is 2 minus 1 = 1. Those two distances are the base and height of a right-angled triangle, so to get the hypoteneuse, use Pythagoras: that gives you that the distance is the square root of (7*7 + 1*1) = sqrt(50) = roughly 7.071. I don't know where the calculus comes in, though.
