Answer:

A relation between x and y such that the pt. (x,y) is equidistant from the points (7,1) and (3,5) :-

a) x+y = 2

b) x-y = 2

c) x+y = 3

If point (x ,y) is equidistant from the points (7,1) and (3,5). So (x,y) is midpoint of line joining (7,1) and (3,5).

Co-ordinates of midpoint of line joining (7,1) and (3,5) can be written as :-

=> x = 5

=> y = 3

Now , x - y = 5-3 = 2

Therefore option (b) is correct.

- b) x-y = 2

Co-ordinates of midpoint of line joining (a,b) and (c,d) is given as :-
