They are alike because a ray is part of a line, a segment is part of a line, and a line is basically a line. They are different because a segment has two end points; a ray has one, and a line is a group of points on a straight path that extends to infinity like a ray extends to infinity in one direction

Rays aren't really lines, since (Euclidean) lines extend infinitely in all directions, so they can't be parallel lines. But that's to fret a bit too much over the wording. Yes, rays, just like lines and line segments, can be parallel to other rays, lines, or line segments.
Plotting points. Graphing lines, line segments, rays, etc.
lines go infinitely in both directions of the line line segments are just a part of the lines rays start at one point and go off into the other direction infinitely
