Answer:
Alternative A
Explanation:
Translation using a vector mens that the first number is the translation of the x-coordinate and the second it the translation of the y-coordinate.
So, translation by vector (-3 4) means substracting 3 units from the x-coordinate and adding 4 units to the y-coordinate, so:
P'=(2-3,-3+4)=(-1,1)
Which corresponds to alternative A.
