Question

In which quadrant does the point lie if:

(i) Both the co-ordinates are positive?
(ii) Both the co-ordinates are negative?
(iii) x-co-ordinate is negative and y-co-ordinate is positive
(iv) x-co-ordinate is positive and y-co-ordinate is negative?

Answer 1

(i) When x-coordinate is positive and y-coordinate is also positive,
the point is in quadrant I.

Therefore, when both the coordinates are positive, the point lies in quadrant I.

(ii) When x-coordinate is negative and y-coordinate is also negative,
the point is in quadrant III.

Therefore, when both the coordinates are negative, the point lies in quadrant III.

(iii) When x-coordinate is negative and y-coordinate is positive,
the point is in quadrant II.

Therefore, when x-coordinate is negative and y-coordinate is positive, the point lies in quadrant II.

(iv) When x-coordinate is positive and y-coordinate is negative, the point is in quadrant IV.

Therefore, when x-co-ordinate is positive and y-co-ordinate is negative, the point lies in quadrant IV.
