Which is the directrix of a parabola with equation x^2=8y

Alright so, After rewriting the equation in a standard parabola, you get:

4 x 2 (y-0) =(x - 0)^2

Simplify it to get:

y= 0-p

y= 0-2

When you simplify that, your answer is:

y=-2

There you go folks, just saved you from reading that long paragraph of an answer the other guy has (I don't even think the answer is in there lol, I think he just wanted to help people solve it but still most people come here for answers)

they are simplified

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
