You start a search for a buried object by marking the center of a filed as (0,0), with coordinates giving distances in yards. Coordinates to the north or east are positive and coordinates to the south or west are negative. You find nothing at (-12,8), so you try a likely-looking spot 3 yards to the east and 11 yard to the south of the first spot. What are the coordinates of the second spot?
