   How about pulling a piece of string taut?  Won't that give a straight line?

Hmmmmmmm ...

"No power on Earth, however great,
Can stretch a string, however fine,
Into a horizontal line
That shall be absolutely straight."

-- Author unremembered, it's in _Fantasia Mathematica_.

Levity aside, either method can make a line straight enough for
purposes of illustration. After all, how about all that irregularity
in the paper, and your desk? That corrupts your drawings too! And
those damned imperfect pencil points! Although I suppose, being a
model of the apex of a cone, they satisfy the philosophical objection
better than some piece of brass or plastic from K-Mart does for a line.
