By using the distance formula

=

(x

−x

)

2

+(y

2

−y

1

)

2

we have

⇒

(x−3)

2

+(y−6)

2

=

(x+3)

2

+(y−4)

2

⇒(x−3)

2

+(y−6)

2

=(x+3)

2

+(y−4)

2

⇒x

2

−6x+9+y

2

−12y+36=x

2

+6x+9+y

2

−8y+16

⇒−6x−6x−12y+8y+36−16=0

⇒−12x−4y+20=0

⇒3x+y−5=0

Hence this is a RELATION between x and y.
