THE SLOPE IS 1 AND THE Y INTERCEPT IS -3, the x is equal to 1, and the -3 is in the place of the y intercept so your answer would be A.
The first step is to multiply the fraction by (3 +3i) / (3 +3i) to delete the i terms from the denominator:
Answer: The equation of an ellipse:

Has vertices at
(
h

,
k
)
Has foci at
(
h

√
a

)
Use the vertices to write 3 equations:
k
=

[1]
h
−
a
=

[2]
h
+
a
=

[3]
Use equations [2] and [3] to solve for h and a:

h
=

h
=

a
=
8
Use the focus to write another equation:
8
=
h
+
√
a

−
b

Substitute values for h and a:
8
