Will givebrainliest and 25 pts ! which lines are the directrices of the ellipse?
x = −4.25 and x = 8.25
x = −3.25 and x = 9.25
y = −4.25 and y = 8.25
y = −3.25 and y = 9.25

The directrix of the ellipse is:

x= -3.25 and x=9.25

Step-by-step explanation:

As we know that for any ellipse equation of the type:

and a>b

The directrix is given by:

where,

Here we have the equation of parabola as:

Hence, we have:

Hence, we have: the directrix as:

Hence, the equation of directrix is:

x= -3.25 and x=9.25
