Correction for Number 10

A coordinate grid is divided into four sections. Quadrant 1 is (+,+), quadrant 2 is (-,+), quadrant 3 is (-,-) and quadrant 4 is (+,-). For example the coordinates (-2, 3) would be in quadrant 2 because (-,+).

The question was in which quadrant is the point with coordinates (11,-6)?

The answer is quadrant 4 because (+,-).
