Answer in Brief

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

  1. Write the co-ordinates of the points Q and R.
  2. Write the co-ordinates of the points T and M.
  3. Which point lies in the third quadrant?
  4. Which are the points whose x and y co-ordinates are equal?

Solution

(1) 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).

(2) 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).

(3) 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.

(4) The co-ordinates of point O are (0, 0).
Thus, O is the point whose x and y co-ordinates are equal.
