Question 114010
from wikipedia


 "In Cartesian coordinates, a parabola with an axis parallel to the y axis with vertex (h, k), focus (h, k + p), and directrix y = k - p, with p being the distance from the vertex to the focus, has the equation with axis parallel to the y-axis"


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


p=-2, h=1, k=2 ___ (x-1)^2=-8(y-2)
