Positive x axis to the left, positive y axis upward
	Positive x axis to the right, positive y axis downward
	Positive x axis to the left, positive y axis downward
	Positive x axis to the right, positive y axis upward

I think it would be: Positive x axis to the right, positive y axis upward
because the guy is pulling it upwards and it is accelerating to the right, but please correct me if I am wrong.

It's left and y upward. I just solved it.
