Step-by-step explanation:
We are given equation of hyperbola
Vertices are (0,-4) (0,4)
we can use formula
vertices : (h , k+a) and (h,k-a)
we can compare and find h , k and 'a'
we can add both equations
we get
now, we can find 'a'
now, we can use foci formula
foci: (h, k + c), (h, k - c)
we know that
so, we can solve for b
now, we can use standard equation of hyperbola
now, we can plug values

Given the two co-ordinates:
A(x1,y1) = (-4,-8)
B(x2,y2) = (-4,0)
Putting them in the distance formula:
