Exercise 3.2
1. Write the answer of each of the following questions:
(i) What is the name of horizontal and the vertical lines drawn
to determine the position of any point in the Cartesian plane?
Answer
\(X \)-axis and \(Y \)-axis are the name of horizontal lines and
vertical lines drawn to determine the position of any point in the
Cartesian plane respectively.
(ii) What is the name of each part of the plane formed by these
two lines?
Answer
The name of each part of the plane formed by these two lines
is:a) \(1^{\text{st}}\) quadrant \( (+x,+y) \)
b) \( 2^{\text {nd }} \) quadrant \( (-x,+y) \)
c) \( 3^{\text {rd }} \) quadrant \( (-x,-y) \)
d) \( 4^{\text {th }} \) quadrant \( (x,-y \) )

2. See Fig. 3.14, and write the following:
(i)
The coordinates of B
The coordinates of B
Answer
For notifying the points shown in the graph. First look at the
horizontal distance of points from Origin.Then look at the vertical distance of point from origin. Distance measured to the right of origin is positive \( x \) axis. And distance measured to the top of origin is positive \(y\) axis. And similarly left and bottom shows negative \(x\) axis and negative \(y\) axis respectively.
The coordinates of B are \( (-5,2) \)
