Exercise 3.3
Question :1. Represent the following points (3, −1), (−2, 4), (1, 2), (−1, 0) and (−3, −5) on a Cartesian plane and also tell in which quadrant do they lie? Give reason for your answer.
Answer :
First, we draw all points on the Cartesian plane.
From the figure, we can find that
(−2, 4) lies in Second quadrant
(3, −1) lies in Fourth quadrant
(−1, 0) lies in Second quadrant
(1, 2) lies in First quadrant
(−3, −5) lies in Third quadrant
Question :2: Plot the points (x, y) given in the following table on the plane, choosing suitable units of distance on the axes and also tell in which quadrant or axis does it lies.

Answer :
Points (x, y) on the plane.
Here, let 1unit = 1 cm
First we draw all the given points on the Cartesian plane.
From the figure, we find that
(−2, 8) lies in Second quadrant
(−1, 7) lies in Second quadrant
(0, −1.25) lies in Fourth quadrant
(1, 3) lies in First quadrant
(3, −1) lies in Fourth quadrant
