Which of the following lines is a locus of equidistant points from the two lines $\begin{aligned} 12x+5y+31 &= 0 \text{ and} \\ -5x+12y+3 &= 0 ? \end{aligned}$

For the three points $P=(-4,0),$ $Q=(0,0)$ and $R=(2,2\sqrt{3}),$ what is the equation of the bisector of the angle $\angle{PQR}?$

Let $\displaystyle y=-\frac{1}{\sqrt{5}}x$ be one of the two bisectors of the angles between two lines $px+qy+r=0, p'x+q'y+r'=0$ which intersect at the point $P=(-2\sqrt{5},2).$ What is the $y$ -intercept of the other bisector?
