## NCERT Solutions for Class 9 Maths Chapter 3 Coordinate Geometry Ex 3.2

Ex 3.2 Class 9 Maths Question 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?
(ii) What is the name of each part of the plane formed by these two lines?
(iii) Write the name of the point where these two lines intersect.

Solution:
(i)
The horizontal line is called x-axis and the vertical line is called y-axis.
(ii) The horizontal and vertical lines divide the plane in four parts. Each part is known as a Quadrant.
(iii) The point where these two lines intersect is known as Origin. Its coordinates are (0, 0).

Ex 3.2 Class 9 Maths Question 2.
See the given figure and write the following:
(i) The coordinates of B.
(ii) The coordinates of C.
(iii) The point identified by the coordinates (-3, -5).
(iv) The point identified by the coordinates (2, -4).
(v) The abscissa of the point D.
(vi) The ordinate of the point H.
(vii) The coordinates of the point L.
(viii) The coordinates of the point M.

Solution:
From the given figure, we have
(i) The coordinates of B are (-5, 2).
(ii) The coordinates of C are (5, -5).
(iii) The point identified by the coordinates (-3, -5) is E.
(iv) The point identified by the coordinates (2, -4) is G.
(v) The abscissa of the point D is 6.
(vi) The ordinate of the point H is -3.
(vii) The coordinates of the point L are (0, 5). On y-axis, abscissa is 0.

(viii) The coordinates of the point M are (-3, 0). On x-axis, ordinate is 0.
