Step-by-step explanation:

1.  +  = 1

SOLUTION:  

The ellipse is in standard form, where h = –2, k = 0, a =  or 7, b =  or 3, and c =  or about 6.3. The  

orientation is vertical because the y–term contains a

2

.

center: (h, k) = (–2, 0)

foci: (h, k ± c) = (–2, 6.3) and (–2, –6.3)

vertices: (h, k ± a) = (–2, 7) and (–2, –7)

covertices: (h ± b, k) = (1, 0) and (–5, 0)
