उत्तर
As we know that:
The distance of a point from y−axis is called its x−coordinate or abscissa.
The distance of a point from x−axis is called its y−coordinate or ordinate.
The coordinate axes divide the plane into four equal parts which are known as quadrants.
The point of intersection of the coordinate axes is called the origin and the coordinates of origin are (0,0).

(Street Plan): A city has two main roads which cross each other at the centre of the city. These two roads are along the North-South direction and East-West direction.
All the other streets of the city run parallel to these roads and are 200 m apart. There are 5 streets in each direction. Using 1cm = 200 m, draw a model of the city on your notebook. Represent the roads/streets by single lines.
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 2nd street running in the North - South direction and 5th 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).
- how many cross - streets can be referred to as (3, 4).
