Edited By Safeer PP | Updated on Jul 29, 2022 02:58 PM IST

NCERT Solutions for Class 9 Maths chapter 3 exercise 3.2 introduces us to the cartesian system. We learned that the number line in earlier classes was the representation of the location of points in one dimension. The cartesian system represents the location of points in two dimensions. The cartesian system was developed by a great French mathematician of the seventeenth century René Déscarte.

NCERT solutions for class 9 maths chapter 3 exercise 3.2 introduces us to many terminologies such as x-axis, y-axis, origin, quadrants. NCERT solutions for Class 9 Maths exercise 3.2 is a foundation exercise for the branch of coordinate geometry as well as all of the chapters that will be covered in subsequent sessions. We gave a broad concept of this in exercise 3.2 Class 9 Maths. the cartesian plane and cartesian axis, along with this how we represent coordinates on the cartesian plane. Along with Class 9 Maths chapter 3 exercise 3.2 the following exercises are also present.

Q1 (i) Write the answer of each of the following questions:

What is the name of horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?

Answer:

The Horizontal line is x-axis and the Vertical line is y-axis.

Q1 (ii) Write the answer of each of the following questions:

What is the name of each part of the plane formed by these two lines?

Answer:

Benefits of NCERT Solutions for Class 9 Maths Exercise 3.2

Class 9 Mathematics chapter 3 exercise 3.1 covers the fundamentals of identifying coordinates in the cartesian plane, which we will need to know for Class 9 Maths chapter 3 exercise 3.3. NCERT exercise 3.2 from chapter 3 of Class 9 Maths will be useful in chapter 7 of Class 10 Math: Coordinate Geometry. NCERT solutions for exercise 3.2 Class 9 Maths chapter 3 will be useful in Class 11 Maths chapter 10 straight line and Class 11 Maths chapter 11 conic section. Exercise 3.2, Class 9 Maths, is also a foundation idea for several joint entrance test themes (JEE Main).
