**NCERT Solutions for Class 9 Maths chapter 3 exercise 3.1 **introduces us to the branch of coordinate geometry. As this is the first time Coordinate Geometry is introduced in the chapter starts with a very basic concept of introduction of the coordinate and coordinate plane. NCERT solutions for Class 9 Maths exercise 3.1 is a base builder exercise for the branch of coordinate geometry and all the chapters that will be studied in further classes. In exercise 3.1 Class 9 Maths, we have given a rough idea about how to write the coordinate of a location how to find the coordinate how it is applied and when we can use it in real life.

** 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.

Class 9 Maths chapter 3 exercise 1 broadly includes many types of activities, examples and observations from which we can speculate the importance of coordination in our life. These examples are about the seat arrangement of students, arrangements about the construction of roads. NCERT solutions for Class 9 Maths exercise 3.1 includes a basic concept of locating a point anywhere in the world or a specific area along with this it also consists of a brief history about the origin of coordinate geometry and its application in real life. Exercise 3.1 Class 9 Maths covers all types of basic questions that can be formed on locating the coordinate. Coordinate geometry has vast uses in the whole world, not in mathematics only this is the idea of whole exercise 3.1 Class 9 Maths trying to enlighten us with.
