Answer:

Step-by-step explanation:
The directrix of the parabola is the horizontal line with the eqaution
The focus of the parabola is at point (-4,10), than the axis of symmetry of the parabola is the perpendicular line to the directrix passing through the focus. Its equation is
The distance between the directrix and the focus is
so
and the vertex is at point 
Parabola goes in positive y-direction, hence its equation is

where
is the vertex, so the equation of this parabola is
