**Q1 ** How will you describe the position of a table lamp on your study table to another person?

**Answer: **

To describe the position of a table lamp placed on the table,

Let us consider the table lamp as P and the table as a plane.

Then, we consider two perpendicular edges of the table as the axes OX and OY.

From OY measure the perpendicular distance of P.

From OX measure the perpendicular distance of P.

Thus, the position of the lamp is then given by;

There are many cross- streets in your model. A particular cross-street is made by two streets, one running in the North-South direction and another in the East-West direction. Each cross street is referred to in the following manner: If the 2 ^{ nd } street running in the North-South direction and 5 ^{ th } in the East-West direction meet at some crossing, then we will call this cross-street (2, 5). Using this convention, find: how many cross - streets can be referred to as (4, 3).

** Answer: **

(i) From the figure:

There is only one cross - streets which can be referred to as (4, 3).

There are many cross- streets in your model. A particular cross-street is made by two streets, one running in the North-South direction and another in the East-West direction. Each cross street is referred to in the following manner: If the 2 ^{ nd } street running in the North-South direction and 5 ^{ th } in the East-West direction meet at some crossing, then we will call this cross-street (2, 5). Using this convention, find: how many cross - streets can be referred to as (3, 4).

** Answer: **

(ii) From the figure:

The cross street as shown by the point

We have located the two cross streets because of the two reference lines.

** 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: **

The name of each part of the plane formed by the x-axis and the y-axis is called "Quadrant".

** Q1 (iii) ** Write the answer of each of the following questions:

Write the name of the point where these two lines intersect.

** Answer: **

The point where x-axis and y-axis both intersect is known as Origin.

** Q2 ** 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 the point D.

(vi) The ordinate of the point H.

(vii) The coordinates of the point L.

(viii) The coordinates of the point M.

** Answer: **

From the figure:

(i) The coordinates of B are

(ii) The coordinates of C are

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

(iv) The point is G identified by the coordinates (2, – 4).

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

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

(vii) The coordinates of the point L are

(viii) The coordinates of the point M are

This Class 9 NCERT book chapter introduces some basic concepts of coordinate geometry and there will be some higher-level concepts in the upcoming classes. Coordinate geometry was initially developed by a mathematician René Déscartes and French philosopher. There are a total of 3 exercises which consist of 6 questions. NCERT solutions for class 9 maths chapter 3 Coordinate Geometry are designed in such a manner so that a student can score maximum marks in the final examination.

Coordinate geometry is an interesting chapter where students get to learn about the position of an object in a plane, the coordinates of the cartesian plane, and so on. For example, ”Imagine a situation where Ramesh knows only the street number of his friend’s house. Would it be easy for Ramesh to find his friend's house, or would it be easier if he had both the street number and the house number?” There are many other situations in real life, in which to find a point, we might be required to describe its position with reference to more than one line. NCERT Solutions for Class 9 Maths Chapter 3 are covering the explanations to each and every question present in the practice exercises.

Interested students can practice class 9 maths ch 3 question answer using the given exercises.
