Answer:
The first one, the one with A' at -4,5
Step-by-step explanation:
To find which graph shows the translation you first find a point that is easy to follow, ideally one that is along an axis.
Point A would be easy to follow, since it's roughly at (0,3) initially.
Then we apply the translation. T (-4,2) means the X value is moved to the left, subtracted 4 units... while the Y value is moved up, adding 2 units.
So, the point A that was at (0,3) becomes A' at (0 - 4, 3 + 2), or (-4,5).
