A ray has only one end point.
No, it has two. A ray has one end point.
A segment has two end points. If a line has one end point, then it must be called ray.
the part with the end point does not, it stops at the end point. But if there is only one end point on a line, the other end does go on forever
A ray has one origin point and no end points. If it had an end point it would be a line.

A perspective vanishing point on the horizon
A straight or curved line truncated at one point.
A ray
If one of the numbers is zero, zero point something or a negative number. Zero point something is a decimal starting with 0, eg. 0.4, 0.123
One connection involves pointy things; the other involves blunt thing. Hence, 'point to point' and 'end to end'. Not really. I'm just being stupid. LOL(:
An interval on the number scale is a set of numbers between two end-point. Thus the closed interval [a, b] comprises all number between a and b as well as the two end points. An interval is open if neither end point is included, and semi-open (or semi-closed) if one end in included and the other is not.
