15. Find a relation between x and y such that the point (x,y) is equidistant from the point
(-2,8) and (-3,-5)
Answers
Step-by-step explanation:
Points (−2,8) and (−3,−5).
Let (x,y) be x
Let (−2,8)=A(−3,−5)=B
AX=BX (length)

=BX

By Distance formula
(x+2)

+(y−8)

+10y+25
4x+4−16y+64=6x+9+10y+25
4x−16y+68=6x+10y+34
Put x and y in RHS
34=2x+26y
⇒34=2x+26y
⇒17=x+12y
This is a reaction of x and y which will follow the Pt. (x,y) if equidistant from A and B.
