Question 170145
write the standard equation for each conic given the following info. 
Parabola with a focus (-2,3) and a directrix x=2 
---------------
Plot the information you have so you can see what is happening.
The vertex is equidistanc from the directrix and the focus
so it must be at (0,3)
--------------------
p is the distance from the vertex to the focus; so p=-2.
Then 4p = -8
-------------------
Equation Form: 
(y-k)^2 = 4p(x-h) where (h,k) is the vertex.
Your Equation:
(y-3)^2 = -8(x)
