## Question

### Solution

Correct option is

7x + 9y – 3 = 0, 9x – 7y – 41 = 0

Firstly make the constant terms (c1c2) positive, then

–4x – 3y + 6 = 0

and     5x + 12y + 9 = 0

∴ The equation of the bisector bisecting the angle containing origin is

or     7x + 9y – 3 = 0

and the equation of the bisector bisecting the angle no containing origin is

or    9x – 7y – 41 = 0.
