The signs of the coordinates in the quadrants are given as follows:
In quadrant I, the coordinates are given as (x,y).
In quadrant II, the coordinates are given by (-x,y).
In quadrant III, the coordinates are given by (-x,-y).
In quadrant IV, the coordinates are given by (x,-y).
Using the above data, drag (6,-1) to quadrant IV.
Drag (-3,4) to to quadrant II.
Drag (2,4) to quadrant I.
Drag (-1,-5) to quadrant III.
