Question

Please help!
Write the equation of a parabola with a vertex at (5, 2) and a directrix y = 1.

Answer 1

x-5=1/4(y-2)^2
y-2=1/4(x-5)^2
x-2=1/4(y-5)^2
y+2=1/4(x-5)^2

Answer 2

use the general form

(x - h)^2 = 4p(y - k)

where (h,k) is the vertex and y = p is the directrix

plug in the values of h,k and p
