## NCERT Solutions for class 9 Maths Chapter 3- Coordinate Geometry 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?

(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 horizontal and vertical lines drawn to determine the position of any point in the Cartesian plane is x-axis and y-axis respectively.

(ii) The name of each part of the plane formed by these two lines x-axis and y-axis is quadrants.

(iii) The point where these two lines intersect is called the origin.

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 (â€“3, â€“5).

iv. The point identified by the coordinates (2, â€“ 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:

i. The co-ordinates of B isÂ (âˆ’5, 2).

ii. The co-ordinates of C isÂ (5, âˆ’5).

iii. The point identified by the coordinatesÂ (âˆ’3, âˆ’5)Â is E.

iv. The point identified by the coordinatesÂ (2, âˆ’4)Â is G.

v. Abscissa means x co-ordinate of point D. So, abscissa of the point D is 6.

vi. Ordinate means y coordinate of point H. So, ordinate of point H is -3.

vii. The co-ordinates of the point L isÂ (0, 5).

viii. The co-ordinates of the point M isÂ (âˆ’3, 0).

From this exercise, you will get an indication about the horizontal and vertical lines used to determine any position in a cartesian plane or know the coordinates of points from the illustration or graphic provided in the textbook. It helps to keep your studies on point with the help of these effective yet simple examples and exercises.
