Question

Find the standard form of the equation of the parabola with a focus at (0, -9) and a directrix y = 9.

Answer 1

these are the answer choices;
y = -1/9 x2

y2 = -36x

y = -1/36 x2

y2 = -9x

Answer 2

so would it be the y^2 = -36x one?

Answer 3

lol thank you so much! would u help me with one more.. these are my practice questions before my assignment lol

Answer 4

post it

Answer 5

Find the standard form of the equation of the parabola with a focus at (3, 0) and a directrix at x = -3.

Answer 6

here are the answer choices;
y = 1/12 x2

-12y = x2

x = 1/12 y2

y2 = 6x

Answer 7

so would it be the -12y = x^2?

Answer 8

??

Answer 9

wait? what ? thats not one of the answer choices

Answer 10

ahh!! i seee! thank you!!
