Question

The point whose abscissa and ordinate have same sign will lie in.

• A. I and II quadrant
• B. II and III quadrant
• C. I and III quadrant
• D. II and IV quadrant

Answer 1

The correct option is C

I and III quadrant

Here x > 0 and y > 0 i.e. both the coordinates are positive.
Such point can lie in I quadrant.
Now for x < 0 and y < 0, both the coordinates (x,y) are negative.
Such points lie in III quadrant.
So the quadrants in which both the x and y coordinates have same sign are either I quadrant or III quadrant.
