Step-by-step explanation:
given points P(3,2) and Q(-1,-5)
let point on y-axis be M (0,y)
PM=√(3-0) ^2 + (2-y) ^2
=√(3) ^2+(2) ^2+(y) ^2-2.(2) . (y)
= √9+4+y^2-4y
=√y^2-4y+13
QM= √(-1-0) ^2+(-5-y) ^2
= √(-1) ^2+(-5) ^2+(y) ^2-2.(-5). (y)
√1+25+y^2-10y
=√y^2-10y+26
now,
PM=QM
y^2-4y+13=y^2-10y+26
-4y+10y =26-13
6y = 13
y=13/6
point (0,13/6)
