If point (x,-2) is in quadrant IV, that means that x is positive, as we move over x units to the right from the origin and down 2 units.If point (-3,y) is in the II quadrant, then we know that y is positive, as we move 3 units to the left of the origin and x units up.
Thus, we know that in (x,y), we have two positive values; we move right x units and up y units from the origin, so the point must be in quadrant I. A is the answer.
Thus, we know that in (x,y), we have two positive values; we move right x units and up y units from the origin, so the point must be in quadrant I. A is the answer.

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.
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.

↧↧↧ Detailed Video Explanation to the Problem ↧↧↧
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

(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!
