Welllll, yes and no.
Technically, they're parallel, because they have the same slope.
But in this particular case, I don't think you'd really say that they're
parallel, because they're the SAME LINE ! If you draw them both
on the same graph, then one lays right on top of the other one, and
you can't even tell that there are two lines there ... it looks like only
one. Every point on one line is also on the other one.
These lines are 'coincident', and I don't think that fits into the
definition of 'parallel'.
