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

Question 1.

Write the answer to each of the following questions:

(i) What is the name of horizontal and 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 name of the horizontal line drawn to determine the position of any point in the cartesian plane is the x-axis. The name of the vertical line is the y-axis.

(ii) The name of each part of the plane formed by the x-axis and y-axis is called quadrants (one-fourth part) numbered I, II, III, and IV anticlockwise from OX.

(iii) Name of the point where these two lines intersect is the origin.

Question 2.

See fig. 3.14 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 point D.

(vi) The ordinate of the point H.

(vii) The coordinates of the point L.

(viii) The coordinates of the point M.

Solution:

According to Fig. 3.14.

(i) The coordinate of B is (-5, 2).

(ii) The coordinate of C is (5, -5).

(iii) The point identified by the coordinates (-3, -5) is E.

(iv) The point identified by the coordinate (2, -4) is G.

(v) The abscissa of the pint D is 6.

(vi) The ordinate of the point H is -3.

(vii) The coordinate of the point L is (0, 5).

(viii) The coordinate of the point M is (-3, 0).
