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 :

  1. What is the name of horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?
  2. What is the name of each part of the plane formed by these two lines?
  3. Write the name of the point where these two lines intersect.

Solution:

  1. Horizontal line is known as X-axis and vertical line is known as 7-axis.
  2. Each part of the plane formed by horizontal and vertical lines is known as quadrant.
  3. Horizontal and vertical lines intersect at the origin.

Ex 3.2 Class 9 Maths Question 2.
