8-2 commentary
Used the coordinates of every two same type frequences to create the ilnear equation (y = ax + b) and then fed it all the matrix coordinates to see which belonged to the line. To get the correct number of antinodes I had to check for |y - ax - b| < 0.0001, otherwise I got around 20 too few.
