for every
of snow (option B is false).
This means that the function modelling this situation is linear function (option A is true and option D is false). Let the equation of this function be Then
Subtract these two equations:
Hence,
The equation of the straight line (the graph of linear function) is (option E is true) This line passes through the point (0,0), because its coordinates satisfy the equation (option C is true).
