Question

Some points are shown in the given figure, With the help of it answer the following questions :

(i) Write the co-ordinates of the points Q and R.
(ii) Write the co-ordinates of the points T and M.
(iii) Which point lies in the third quadrant ?
(iv) Which are the points whose x and y co-ordinates are equal?

Answer 1

(i) The x co-ordinate of a point is its distance from the Y-axis and y co-ordinate of a point is its distance from the X-axis.

The co-ordinates of point Q are (−2, 2) and the co-ordinates of point R are (4, −1).

(ii) The x co-ordinate of every point on the Y-axis is 0 and the y co-ordinate of every point on the X-axis is 0.

The co-ordinates of point T are (0, −1) and the co-ordinates of point M are (3, 0).

(iii) The point whose x co-ordinate is negative and y co-ordinate is negative lies in the third quadrant.

Thus, the point S(−3, −2) lies in the third quadrant.

(iv) The co-ordinates of point O are (0, 0).

Thus, O is the point whose x and y co-ordinates are equal.
