These solutions serve as a valuable resource to aid in understanding and mastering the mathematical concepts presented in this exercise. Along with Class 9 Maths chapter 3 exercise 3.1, the following exercises are also present.

## Access Coordinate Geometry Class 9 Chapter 3 Exercise: 3.1

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 $'a'\ cm$ of P.

From OX measure the perpendicular distance $'b'\ cm$ 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).

(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).

(ii) From the figure:

The cross street as shown by the point $B(3,4).$

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