Answer
ellipse, directrix is parallel to the polar axis, $3$ units above the pole.
Work Step by Step
Given $r=\frac{6}{8+2sin\theta}=\frac{3/4}{1+\frac{1}{4}sin\theta}$, we have $e=\frac{1}{4}\lt1$, thus it is an ellipse. From the equation and with the $sin\theta$ term, we know $p=3$ and the directrix is parallel to the polar axis, $3$ units above the pole.
