A parabola is the locus of points equidistant from a fixed line (the directrix) and a fixed point (the focus).
Put the equation in vertex form,
The equation in this form tells us that the vertex is at (h,k) = (-1,-5).
It also tells us that
-->
p is the directed distance from the directrix to the vertex, so from the directrix to the vertex is -1/4. Since the vertex is (-1,-5), the directrix is the line x = -3/4.
p is also the directed distance from the vertex to the focus; since the vertex is (-1,-5), the focus is (-5/4,-5).
So this parabola is the set of points equidistant from the line x=-3/4 and the point (-5/4,-5).
