Unit test issue in C2_W2 programming lab exercise 2

[Igor_Kuts]

Please, help, i am hardstuck and have zero clue about what is wrong here.

Grader gives me 98/100 score because of this problem.

Is there anything that i am missing here or it is just a bug / feature?)

Predictions are so far off from expected values =/
And one more thing that cofuses me is that unittest expect an integer output value

Inside the function you dont have any variables such as m_numpy but just m, b. You need to use the variables inside the parameters of the function.
