In Fig. 3.6, LM is a line parallel to the y-axis at a distance of 3 units. What are the coordinates of the points P, R and Q

Solution:

Given, LM is a line parallel to the y-axis at a distance of 3 units.

We have to find the coordinates of the points P, R and Q.

The perpendicular distance of the point P from the x-axis is 2 units and y-axis is 3 units.

The coordinate of the point P = (3, 2)

The perpendicular distance of the point R from the y-axis is 3 units.

The point R lies on the positive x-axis.

The coordinate of the point R = (3, 0)

The perpendicular distance of the point Q from the x-axis is 1 unit and negative y-axis is 3 units.

The coordinate of the point Q = (3, -1)
