This method is designed to determine which of the following is true about two lines: 1. They are the same line. 2. They are parallel lines. 3. They are perpendicular lines.; or 4. None of the above. The input parameters will be the integer values of the coefficients and constant for each line in two different arrays. For example lineType({4,6,1},{3,8,-2}) represents the lines: 4x+6y=1 and 3x+8y=-2. The method returns a 1, 2, 3, or 4 corresponding to the numbered possibilities above. So lineType({4,6,1},{3,8,-2}) returns a 4 since these lines are not the same, parallel, or perpendicular. Note that NONE of the lines will be horizontal or vertical lines in this problem.
