 Apr25 revised Calculating completed percentage of a jigsaw puzzle edited title Apr25 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.

(I think I just took that for granted.) May25 comment Finding out whether two line (segments) intersect I think this is essentially what Thomas described at the end of his answer. May25 awarded Editor May25 comment Finding out whether two line (segments) intersect I updated my question to clarify that I am trying to figure out if the line "segments" intersect. May25 revised Finding out whether two line (segments) intersect I clarified that I wanted to know whether two line segments intersect (not two lines as I realize now that if two lines are not parallel they will eventually intersect). May25 asked Finding out whether two line (segments) intersect May24 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.

May24 comment Finding any point on a line if you know the slope and $y$-intercept. Thanks Marvis...I'm a bit fuzzy on my algebra. That cleared it right up. May24 awarded Student May24 comment Finding any point on a line if you know the slope and $y$-intercept. 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? May24 asked Finding any point on a line if you know the slope and $y$-intercept.
