A given point, one of whose coordinates are positive and the other is negative, lies in the ______ quadrant.

• A. III
• B. either II or IV
• C. I
• D. cannot say

Answer 1

The correct option is B either II or IV

In the II quadrant, the x-coordinate is negative and the y-coordinate is positive.
In the IV quadrant, the x-coordinate is positive and the y-coordinate is negative.
So, a point whose one coordinate is positive and the other is negative, lies in either II or IV quadrant.
So, option (b) is correct.
