KSEEB Solutions for Class 9 Maths Chapter 9 Coordinate Geometry Ex 9.2 are part of KSEEB Solutions for Class 9 Maths. Here we have given Karnataka Board Class 9 Maths Chapter 9 Coordinate Geometry Exercise 9.2.

## Karnataka Board Class 9 Maths Chapter 9 Coordinate Geometry Ex 9.2

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) In a Cartesian plane, to determine the position of any point, the horizontal line is called the x-axis. A vertical line is y-
The y-coordinate is also called the ordinate.
Horizontal line → xOx’
Vertical line → yOy’

(ii) The name of each part of the plane formed by these two lines is called Quadrant.
I Quadrant → xOy
II Quadrant → yOx’
III Quadrant → x’Oy’
IV Quadrant → y’Ox

(iii) The name of the point where these two lines intersect is called the origin. Coordinates of origin are (0. 0).

Question 2.
See Fig.9.14, and write the following: Solution:

1. The coordinates of B : (-5, +2)
2. The coordinates of C. : (+5, -5)
3. The point identified by the coordinates (-3, -5) : E.
4. The point identified by the coordinates (2, -4) : G.
5. The abscissa of the point D : 6
6. The ordinate of the point H: -3
7. The coordinates of the point L : (0, +5)
8. The coordinates of the point M : (-3, 0).
