comment Calculating completed percentage of a jigsaw puzzle
The answer/solution must be perceptually correct because the goal is to analyze the progress of a jigsaw puzzle and determine how much is completed. To a real person, you wouldn't count two halves of the puzzle that are fully assembled as having any more than one match left, though technically speaking, there are two.

comment Finding out whether two line (segments) intersect
That is very true about the need to check the y as well. (I think I just took that for granted.)

I think this is essentially what Thomas described at the end of his answer.

I updated my question to clarify that I am trying to figure out if the line "segments" intersect.

comment Finding any point on a line if you know the slope and $y$-intercept.
This explanation really helped me as well...I was torn on which answer to accept. Thanks for the effort.

Thanks Marvis...I'm a bit fuzzy on my algebra. That cleared it right up.

This is exactly what I was wondering, but I'm a little confused as to how 3x - 3 makes x = 1. Sorry for the ignorant question but could you clarify?
