Answer:
the first one would actually negative because to the left is negative and to the right is positive. and you got the y wrong, that is actually a 2 because you dont include the line you count from, making it (-3,2).
the second one would be perfectly correct.
the third one is actually (-2,-2) and i have no idea how you got that answer, how you would count it 0, its to the left -2 and down -2.
the fourth one, would be actually (-6,-1), remember, a point goes (x,y)
