  1. A \(2 x+y-5=0\)
  2. B \(2 x-y+5=0\)
  3. C \(2 x+y+5=0\)
  4. D \(2 x-y-5=0\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(2 x+y-5=0\)

Step-by-step Solution

Detailed explanation

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 \(A B\). Now, the mid-point of \(A(3,4)\) and \(B(-1,2)\) is \(M\left(\frac{3-1}{2}, \frac{4+2}{2}\right)=M(1,3)\)…
