The line, itself, is a subset (though not a proper subset).
A ray is a subset of a line with one end-point which extends in only one direction.
A line segment is a subset of a line with two end points.
A point is a subset of a line.
Finally, nothing is a subset (the null subset) of a line.

A line has infinitely many subsets, not just three. Any collection of points on the line constitute a subset.

We use words we know to define new terms in geometry. The words point, line and plane have no other words in geometry to describe them They are the building blocks.
