Find the Vertex, the Focus, and the Directrix of the Parabola

Find the vertex, the focus, and the directrix of the parabola.
- $$\mathrm { x } ^ { 2 } - 10 \mathrm { x } + 8 \mathrm { y } + 9 = 0$$

A) Vertex: $\left( 5 , - \frac { 1 } { 2 } \right)$ ; Focus: $( 5 , - 6 )$ ; Directrix: $\mathrm { y } = - 10$
B) Vertex: $\left( 5 , \frac { 15 } { 8 } \right)$ ; Focus: $( 5 , - 6 ) ;$ Directrix: $y = \frac { 17 } { 8 }$
C) Vertex: $\left( 5 , \frac { 9 } { 2 } \right)$ ; Focus: $( 5,4 )$ ; Directrix: $y = 0$
D) Vertex: $( 5,2 )$ ; Focus: $( 5,0 )$ ; Directrix: $y = 4$
