Which line does exist, which line doesn't? I guess we agree, that the
line of slope = 1 does exist, right? And the line of slope = 10^100
does exist, right? If not all of the infinitely many lines do exist,
you need to define, which of these lines are the existing ones, and
which lines are the non-existing lines. That's math (not about
processes and time).
