Answer:
Non Linear

Linear equations can be represented by the following:
Y=mx+b
Ax+By=C
Y-y1=m(x-x1)
This equation can't be represented as ANY of these. It is, however, able to be converted to the standard form of quadratic equations.

-- If you go outside at the same time every night and look at
some familiar stars, you'll see each of them them move westward

-- The reason for that apparent motion is the real motion of the
Earth in its orbit around the sun, at almost exactly 1 degree in
every 24 hours.
(average during a whole year is 0.9856 degree per day.)
