Background information you need to know: the four quadrants of the coordinate system start in the upper right quadrant at I and go counter-clockwise so that the upper left quadrant is II, lower left is III, and lower right is IV.

In quadrant IV, x coordinates are positive but y coordinates are negative. Thus, x must be positive. In quadrant II, x coordinates are negative but y coordinates are positive. Thus, y must be positive.

If both x and y are positive, then point (x, y) must be in the upper right quadrant, which is quadrant I. So the answer is A.

Given that Points (x, -2) and (-3, y) are in quadrants IV and II, respectively and xy ≠ 0. We need to find in which quadrant is point (x,y)?

Now, xy ≠ 0
=> Neither x nor y is equal to 0

Refer below image to understand the sign of variables in a x-y plane



(x,-2) is in IV Quadrant
=> x is positive

(-3,y) is in II Quadrant
=> y is positive

=> (x,y) both are positive
=> (x,y) will be in I Quadrant

So, Answer will be A
Hope it helps!
