Answer:
Step-by-step explanation:
A(10,10) B(b,10b)
ax-2y=30

Divide both parts of the equation by 10:
a=5
Hence,
5x-2y=30
5(b)-2(10b)=30
5b-20b=30
-15b=30
Divide both parts of the equation by -15:
b=-2
Thus,
a=5 b=-2


Divide both parts of the equation by 2:
2.5x-15=y

The equation of the perpendiqular bisector
Hence,
