Write the coordinates of each of the points P, Q, R, S, T and O from the Fig. 3.5
Solution:
Given, the figure represents the points O, P, Q, R, S and T plotted on the graph.
From the figure, we observe that
The points P and S lie in the first quadrant.
In first quadrant the abscissa and ordinate are positive
The perpendicular distance from x-axis is 1 unit and y-axis is 1 unit.
Coordinates of P = (1, 1)
The perpendicular distance from x-axis is 1 unit and y-axis is 2 units.
Coordinates of S = (2, 1)
The point Q lies on the negative y-axis.
So the ordinate is 0
Coordinates of Q = (-3, 0)
The point R lies in the third quadrant.
In third quadrant the abscissa and ordinate are negative
The perpendicular distance from x-axis is 2 units and y-axis is 3 units.
Coordinates of R = (-3, -2)
The point T lies in the fourth quadrant.
In the fourth quadrant, abscissa is positive and ordinate is negative.
The perpendicular distance from x-axis is 2 units and y-axis is 4 units.
Coordinates of T = (4, -2)
The point O is the intersection of both the axes.
The point O is the origin.
Coordinates of O are (0, 0).
