I had an issue with a division by zero in the find_intercepts function (#534).

Apparently this is caused by numpy.linalg.solve which sometimes does not detect the singularity of the input matrix and thus does not throw an exception (numpy/numpy#10471).

This pull request would fix this issue by detecting solutions with zeros.
