A(2,-5) B(-2,9) P(0,y)
(2-0)^2 + (y+5)^2= (0+2)^2 + (y-9)^2
2^2 + y^2 + 25 + 10y = 2^2 + y^2 +81 -18y
4 + 25 -10y = 4 + 81 -18y
8y = 85 -29
y = 56/8
y = 7
So P(0,7)
(2-0)^2 + (y+5)^2= (0+2)^2 + (y-9)^2
2^2 + y^2 + 25 + 10y = 2^2 + y^2 +81 -18y
4 + 25 -10y = 4 + 81 -18y
8y = 85 -29
y = 56/8
y = 7
So P(0,7)
