On second prompt, it asks you to create a function to calculate the difference between a point and the linear function. Can someone explain the syntax/logic for the point input from the function and how within the function point is then designated as x_point, y_point?

def calculate_error(m, b, **point**):

**x_point, y_point = point**

y = m*x_point + b

distance = abs(y - y_point)

return distance
