find the relation between x,y, if the point [x,y] is to be equidistant from[6,-1],[2,3]
Answers
Answer:
Let the points be P(x,y), A(6,-1) and B(2,3).
AP2 = (x-6)2 + (y+1)2
BP2 = (x-2)2 + (y-3)2
Given, 9(x,y) is equidistant from (6,-1) and (2,3)
(x-6)2 + (y+1)2 = (x-2)2 + (y-3)2
x2 - 12x + 36 + y2 + 2y + 1 = x2 - 4x + 4 + y2 - 6y + 9
-12x + 36 + 2y + 1 = - 4x + 4 - 6y + 9
-8x + 8y = -24
-x + y = -3
x - y = 3.

find the relation between x,y, if the point [x,y] is to be equidistant from[6,-1],[2,3]
ANSWER -
Let the points be P(x,y), A(6,-1) and B(2,3).
AP2 = (x-6)2 + (y+1)2
BP2 = (x-2)2 + (y-3)2
Given, 9(x,y) is equidistant from (6,-1) and (2,3)
=> (x-6)2 + (y+1)2 = (x-2)2 + (y-3)2
=> x2 - 12x + 36 + y2 + 2y + 1 = x2 - 4x + 4 + y2 - 6y + 9
=> -12x + 36 + 2y + 1 = - 4x + 4 - 6y + 9
=> -8x + 8y = -24
=> -x + y = -3
x - y = 3. ( ANSWER)
