## Question

### Solution

Correct option is

2x + 4y – 11 = 0

Let P ≡ (1, 1)   and    Q ≡ (2, 3)

The perpendicular bisector (L) of PQ will pass through R (the midpoint of PQ).   Now equation of L: slope = –1/2 passing through R (3/2, 2) is:

y – 2 = –1/2(x – 3/2)

or               2x + 4y – 11 = 0 is the required equation.
