No, it has an endpoint, but the other end (with the arrow) continues infinitely.

Who knows? Probably not, but you can never assume.
There are infininte numbers that fit this case.
A single ray of light can travel in infinitely many different directions.
yes
No, a ray has a starting point, but then it extends on forever in one direction.
An opposite ray is a pair of rays that share the same endpoint and extend in opposite directions. This can be visualized as two rays emanating from a common point but extending in opposite directions along the same line.
A ray (line extends in both directions and line segment has two endpoints)
No, a ray extends infinately in one direction; but this can be any direction at all
NO it does not, a ray extends from one point and goes on forever in ONLY ONE direction.
That would be a line.
There are infininte combinations, such as 5+5+2.5+2.5.
