Question

Find the quadrant in which the following points lie:

(i) (5, 10); (ii) (−8, 9); (iii) (−800, −3000); (iv) (8, −100).

Answer 1

(i) From the point, we observe that i.e., both x and y are positive.

This point lies in quadrant I.

(ii) From the point, we observe that i.e., x is negative and y is positive.

This point lies in quadrant II.

(iii) From the point, we observe that i.e., both x and y are negative.

This point lies in quadrant III.

(iv) From the point, we observe that i.e., x is positive and y is negative.

This point lies in quadrant IV.
