Let P=(-1,0), Q=(0,0) and R=(3,3 3 ) be three points. Then the equation of the bisector of the PQR is

Options

  1. A3 x +y=0
  2. Bx+ 3 2 y=0
  3. C- 3 2 x+y=0
  4. Dx+ 3 y=0

Correct answer

A. 3 x +y=0

Step-by-step solution

Given P (-1,0), B =(0,0), R=(3,3 3 ) Now slope of line Q M= 2 3 =- 3 Equation of line Q M=y- 3 x=0 3 x+y=0
