Given,

 Vertex (0,0) And  focus (-2,0)

As vertex of the parabola is (0,0) and focus lies in the negative X-axis, The parabola will open towards left, And the standard equation of such parabola is 

y^2=-4ax

Here it can be seen that a=2

So, the equation of a parabola is 

\Rightarrow y^2=-4ax\Rightarrow y^2=-4(2)x

\Rightarrow y^2=-8x.
