You can put this solution on YOUR website! Desribe the possible locations, in terms of quadrants or axes, for the graph of (x,y) if x and y satisfy the given conditions.
a. xy>0
x and y must have the same sign
That is true in the 1st and the 3rd quadrants.
--------------
b. xy<0
x and y must have opposite signs.
That is true in the 2nd and 4th quadrants.
----------------
c. xy=0
If x=0 y can be any value. That describes the x axis.
If y=0 x can be any value. That describes the y axis.
------------
Cheers,
Stan H.
