Answer:
(3,3) (0,-3)
Explanation:
You start at the orgin point, which is (0,0) and work your way, first, across the X axis and see there is no point and go down on the Y axis, and see there is a negative -3 there. (0,-3)
Then you go back to the orgin point again and try to see for another point, and same steps from the first part get you (3,3).
