Okay, Once Again The Value Of X Has Been Lost & It's Up To You To Find It.
1st. Divide Both Sides By -1/2, Dividing By -1/2 Is The Same As Multiplying By -2
2nd. Subtract 4 From Both Sides
3rd. Divide By The Coefficient Of X
4th.
The 3rd Step Is Technically Not Needed, Because We Know The Coefficient Of X In The Equation Is 1, If It Was Any Other Value, Then It's Needed.

Answer:
(0, -4)
Step-by-step explanation:
The given relations tell you ...
p = 16/4 = 4
Then the equation of the parabola is ...
x^2 = -16y
It opens downward, so the focus is below the vertex. The distance between the vertex and the focus is p = 4, so the focus is (0, -4).
__
The attached graph shows the parabola, along with its focus and directrix.
