Find a relation b

Answer :

Given that AP=BP

Distance between two points (x1,y1) and (x2,y2) is given by


(x1-x2)2 + (y1-y2)2


Length of AP=√ (x-2)2 + (y-5)2


Length of BP=√ (x + 3)2 + (y-7)2


AP=BP


√ (x-2)2 + (y-5)2 =√ (x + 3)2 + (y-7)2


Squaring both sides,


(x-2)2 + (y-5)2 = (x + 3)2 + (y-7)2


(x2 + 4-4x) + (y2 + 25-10y) = (x2 + 9 + 6x) + (y2 + 49-14y)


29-4x-10y=58 + 6x-14y


10x + 29=4y
