Given a pair of equations of the form:
And
If
such that:
and
then the graphs of the two functions will be a pair of distinct parallel lines.
On the other hand, if
such that:
and
Then the graphs of the two functions will be two instances of the identically same line.
Another way to look at it, and probably easier to tell just by looking:
