'Parallel' means parallel TO something else. A single line all by itself
is not "a parallel line", until we know the other line that it's parallel TO.
There are an infinite number of lines that pass through (0, -2).
Give us another line, and we'll find the one that's parallel to it.

Since you need the vertex, and knowing the vertex will tell you the axis of symmetry, it is convenient to put the equation in vertex form.
.. -x^2 -4x +1
.. = -(x^2 +4x) +1
.. = -(x^2 +4x +(4/2)^2) +1 -(-(4/2)^2) . . . . complete the square
.. = -(x +2)^2 +5
The vertex is (-2, 5).
The axis of symmetry is x = -2.
