Any good answers will get medals. If you can just explain how to do it I can find the answer myself too.

anonymous · Answer

right down a few coordinates with opposite signs.  (-x, y), (x, -y).  I think you will see what they are getting at.

Any point is in the form (x,y)


If x is positive then y is negative (since "The coordinates of an ordered pair have opposite signs"). This would mean that the point is in the fourth quadrant. 

OR

If x is negative, then y is positive. So this point would be in the second quadrant.
