The right angle bisector of the line segment joining points A(3,4) and B(−1,2) passes through the mid-point of A and B perpendicular to line segment AB.
Now, the mid-point of A(3,4) and B(−1,2) is
M(‌

)=M(1,3)
and slope of right angle bisector is =−‌

=−2
∴ Equation of required right angle bisector is
y−3=−2(x−1)
⇒‌‌2x+y=5 or 2x+y−5=0
