SOLUTION IS IN THE ATTACHMENT

Coordinate geometry is the branch of mathematics which deals with the position of an object lying in a plane.

Each  point in cartesian plane has two coordinates X coordinate and Y coordinate.

The X co-ordinate is called the abscissa.

The Y co-ordinate is called the ordinate.

Coordinates X and Y taken together are called coordinates of a point. (x,y) is called an ordered pair.

SECTION FORMULA:

Coordinates of point are :

[(m1x2 + m2x1)/m1+m2 ,( m1y2 + m2y1)/m1+m2]
