Lepiej chyba by było zastosować opis parametryczny, czyli (x,y)=f(k),
interpolacja by wyglądała wtedy tak (nie ma problemu z x1==x2)

def get_interpolated(x1, y1, x2, y2):
  def interpolated(k):
    return x1+(x2-x1)*k, y1+(y2-y1)*k
  return interpolated

>>>f = get_interpolated(0.0, 0.0, 10.0, 5.0)
>>>print f(0.0)
(0.0, 0.0)
>>>print f(1.0)
(10.0, 5.0)
>>>print f(0.5)
(5, 2.5)
