The equation represents an ellipse.

Which lines represent the approximate directrices of the ellipse? Round to the nearest tenth.

A. x = - 8.6 and x = 8.6

B. x = - 6.6 and x = 10.6

C. y = - 8.6 and y = 8.6

D. y = - 6.6 and y = 10.6

The answer is D. y = - 6.6 and y = 10.6

Step-by-step explanation:

First of all, this is an ellipse with a vertical major axis so it would have to be y = #

d=a2/c

d is the distance between the center and the directrix.

a = 8 b=3

c2=a2-b2

=64-9

c2=55

= about 7.4

d=64/7.4

=8.6

y = 2+8.6

y=10.6

y=2-8.6

y=-6.6
