Correct output:
---------------
Length = 3.00  Slope = -0.00
P = (1.0,2.0)  Q = (4.0,2.0)

Length = 2.00  Slope = 1.00
P = (0.0,0.0)  Q = (1.414,1.414)

Length = 2.50  Slope = -2.00
P = (5.5,2.0)  Q = (6.618,-0.236)

Length = 0.50  Slope = -5.00
P = (0.0,0.0)  Q = (0.098,-0.49)

Length = 1.41422  Slope = 1.00
P = (0.0,-1.0)  Q = (1.0,0.0)

Length = 24.51  Slope = 0.75
P = (-2.4,5.8)  Q = (17.208,20.506)
