Nice problem Swapnali! Since it has a floating-point answer, you should specify how many significant digits you're looking for, or include a tolerance term in your test suite.
Thanks Ned. Can you please show me how can I add a torelance term for the answer in test suite?
something like this:
assert(abs(BestFit(x,y)-y_correct)<1e-5)
please allow for tolerance in precision of test case answers
