--------------------------------------------
1.) Vertex at (2,5) Focus at (2,-3)
2.) Diretrix: x= 3/4 Focus: (5/9, -3)
--------------------------------------------


The directrix for your example (1) will be the line y=13.


You can find the equations using these as guidance:

derive parabola equation given known focus and directrix, vertex not at origin

if vertex is at origin, derive equation for parabola given focus and directrix
