B, it is located on the 2nd quadrant
Im not sure what the question is asking but my guess would be c)18.
Y2-Y1. 77-11 66 11
———— = ———- = —- = —
X2-X1 42-6 36 6
Answer:

Step-by-step explanation:
An ellipse with vertices (-8, 0) and (8, 0)
Distance between two vertices = 2a
Distance between (-8,0) and (8,0) = 16
2a= 16
so a= 8
Vertex is (h+a,k)
we know a=8, so vertex is (h+8,k)
Now compare (h+8,k) with vertex (8,0) and find out h and k
h+8 =8, h=0
k =0
a minor axis of length 10.
Length of minor axis = 2b
2b = 10
so b = 5
General formula for the equation of horizontal ellipse is

a= 8 , b=5 , h=0,k=0. equation becomes
