☆ ANSWER ☆:-
● Co-Ordinate Points:- The x-coordinate and y - coordinate of the point in the plane is written as (x, y) for point and is called the coordinates of the point.
●Co-Ordinate System:- the position of a point in a plane is determined with reference to to fixed mutually perpendicular lines called the co-ordinate Axes.
●Origin:- The Point Where These 2 lines intersect.
●Quadrant:- Each part of the plane formed by these two lines.
● a) Horizontal Line:- x axis
b) Vertical Line:- y axis.
● a) Abscisa:- x axis
b)Ordinate:- y axis.
● Ordered Pair:- a pair of numbers a and b listed in a specific order with 'a' at the first place and 'b' at the second place is called and ordered pair (a,b).

Quadrants: The coordinate axes divide the plane into four parts which are known as quadrants.
Ordered pair : A pair of numbers a and b listed in a specific order with 'a' at the first place and 'b' at the second place is called an ordered pair (a,b)
- a - X - coordinate | abscissa of P.
- b - Y - coordinate | ordinate of P.
- The point of intersection of the coordinate axes is called the origin.
The coordinates of origin are (0,0)
- Every point on the x-axis is at a distance o unit from the xx-axis. So its ordinate is 0.
- Every point on the y-axis is at a distance of unit from the yy-axis. So, its abscissa is 0.
