Question 399871: problem: write the eqation in standard form for each parabola.
vertex (0,0), Focus (-8,0)
I know the proper equation. I just do not know which. the one with y= or x=. also when given the foci how do you get the directix?

If Vertex (0;0),Focus (p;0) then the equation in standard form for parabola is (directrix is line x=-p)
.
Focus (-8;0) p=-8
if you ask about directrix: if Focus (-8;0) directrix is line x=8
.
.
If Vertex (0;0),Focus (0;p) then the equation in standard form for parabola is (directrix is line y=-p)
