Normally 2 equidistance lines are needed to designate them as parallel lines.
If we say parallel lines, we mean different lines. However, we can say that the line can be parallel to itself if we move it to another dimension. For example, if the line lives in 2D, we can paralleled move it it in the 3D space, and move it again where it was, or vice versa. The beauty is that this line has a unique position on the plane, but in 3D it has infinitely many positions without breaking the condition, the same direction.

Is the equator perpendicular or parallel?
A single line cannot be perpendicular or parallel. These are attributes of two (or more) lines.
Is y equals -5x 9 parallel or perpendicular?
y = -5x + 9 is the equation of a straight line. It cannot be parallel or perpendicular by itself, you need another line to compare it to.
Is 2x equals y plus 8 a parallel line or a perpendicular line?
One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.
Is -x plus 2y equals 6 a parallel line or a perpendicular line?
One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.
Is a roof a parallel line?
A single entity cannot be parallel. If it is parallel, it has to be parallel to something else. It is like being a friend. You cannot be a friend in abstract. You have to be a friend with someone. The two of you are friends, not just you alone.
