Question 872135: write the equation for the ellipse and find your foci points:
v1 and v2: (-9,5) and (7,5)
cv1 and cv2: (-1,11) and (-1, -1)
I attempted this problem and found that my center was at (-1, 5)
the equation formula that I have to use is (x-h)^2 + (y-k)^2
all over a^2 b^2

write the equation for the ellipse and find your foci points:
v1 and v2: (-9,5) and (7,5)
cv1 and cv2: (-1,11) and (-1, -1)
***
Given ellipse has a horizontal major axis
Its standard form of equation: a>b, (h,k)=coordinates of center
center: (-1,5)
length of horizontal major axis=16=2a
a=8
a^2=64
length of co-vertices=12=2b
b=6
b^2=36
c^2=a^2-b^2=64-36=28
c=√28
foci:(√28,5),(-√28,5)
equation of given ellipse:
