A learner places (-6, -1) in Quadrant II after reading only its x-coordinate. Where does the point actually lie?

Explication

Both coordinates stand below zero, so the point lies left of the y-axis and beneath the x-axis, in the region diagonally opposite the all-positive one. The learner names a region holding points that lie left of the y-axis but above the x-axis, and a y-coordinate below zero rules that out; the four regions also cover the whole plane away from the axes, so a pair of negative coordinates cannot fall outside them all.
