The second number is on the vertical side, and the same thing. In this case, -1 1/2 would be on the bottom in between the -1 and the arrow.
Now find the place where the two intersect on the coordinate plane, and put a dot there to mark the coordinate.
I believe that would be Mesopotamia, the seat of the Sumerian and Akkadian civilizations.
