Find the vertex, focus, and directrix of the following?

Question

parabola, and sketch

(x+8)^2 = 8(y+1)

thanks if you can help
this is on a practice test and no anwers were given.

Answer 1

Standard form is x^2 = 4cy where the focus is c units from the vertex. Vertex is ( -8,-1) , hence directrix is y = -3 and focus is ( -8,1)
