It   DEPENDS   on which point is in the fourth quadrant   (the info which you missed to provide).

I think it's obvious that the given point had to be (p,q) in the fourth
quadrant.

All first quadrant points are 

All second quadrant points are 

All third quadrant points are 

All fourth quadrant points are 

So if (p,q) is a point in the fourth quadrant, then p is 
POSITIVE and q is NEGATIVE, so -p is NEGATIVE.  So (q,-p) is 
(NEGATIVE,NEGATIVE) so it's in the third quadrant.
