Vectors!

Last weekend I derived an equation to find the distance from a line to a point and implemented this into an algorithm in a vector class. In order to do this in an appealing way I taught myself about nested classes (quite simple) and Image IO. (Although I couldn't recite the code, this also proved to be fairly simple.) Currently I'm trying to figure out how to make an efficient and simply way to present a class that will run saving the vectors and generate a corresponding image to run alongside the vectors, with my goal being making a randomly generated top-down game.

I don't have any major commentary on the class except that some of the worksheets did seem superfluous, though I did get a fair amount of the questions wrong so I can't honestly present any criticism on the issue.
