Solution
Thinking process
(i) Firstly, draw the perpendicular lines from the point to the coordinates axes.
(ii) Further, measure the distance from intersecting points to the origin along with their sign.
(iii) Finally, write the x unit distance and y unit distance in a pair.
Here, point P and S lie in I quadrant s their both coordinates will be positive.
Coordinates of Point P are (1, 1).
Now. Perpendicular distance of S from x-axis is 1 and from y-axis is, so coordinates of S are (2,1).
Point Q lies on the x-axis in the negative direction so its y-coordinates will be zero and x-coordinate will be -3.
So, coordinates of Q are (-3, 0).
Point R lies in III quadrant. So, its both coordinates will be negative. Now, its perpendicular distance from x-axis is 3 and from y-axis is 2, So coordinates of point R are (-2, - 3).
Point T lies in IV quadrant. So, its x-coordinate will be positive and y-coordinates will be negative. Now, its perpendicular distance from x-axis is 2 and from y-axis is 4, So coordinates of T are (4,-2).
Point O is the intersection of both axes, so it is the origin and its coordinates are O(0, 0).
