what is an equation of a parabola with the given focus?
focus: (-2,0)
can you write the steps out to me? this was all the information i was given

The answer to your question is y² = -8x

Step-by-step explanation:

The equation of a horizontal parabola with vertex (0, 0) is:  y ² = -4px

and p is the distance from the vertex to the focus, in this problem

p = 2.

Substitution

                            y² = -4(2)x

Simplification

                            y² = -8x            

what are the options? ?
