Another Angle Bisector Problem

Geometry Level pending

If the three vertices of a triangle are A A ( 1 , − 3 ) (1,-3) , B ,B ( − 2 , 3 ) (-2,3) and C C ( − 8 , 0 ) (-8,0) , then the equation of the bisector of angle A B C ABC which meets opposite side at D D can be

18 x − 6 y + 54 = 0 18x-6y+54=0 5 x + 17 y + 52 = 0 5x +17y+52=0 8 x + 15 y − 76 = 0 8x+15y-76=0 17 x − 5 y + 52 = 0 17x-5y+52=0

18x - 6y + 54 = 0 the only one that passes through (-2,3).
