Given that the parabola y squared = - 8x, then the Quasilinear equation of the parabola is?

Given that the parabola y squared = - 8x, then the Quasilinear equation of the parabola is?

A:
Y squared = - 8x
y²=-8x=2px
p=-4
p/2=-2
So: the Quasilinear equation is x = - P / 2 = 2
So: the Quasilinear equation is x = 2, the focus f (- 2,0)
