1) translation of 3 units to the right and 3 units down.
2) It is not a translation.
How to identify a translation?
Remember that a translation only moves the graph, it does not change the size nor the orientation of the figure.
For example, in the diagram number 2 we can see that the orientation of the two triangles is different, so there we don't have a translation.
Now for diagram 1, to identify the translation just compare equivalent vertices:
A = (-2, 4)
A' = (1, 1)
The difference gives:
A' - A = (1, 1) - (-2, 4) = (1 + 2, 1 - 4) = (3, -3)
This is a translation of 3 units to the right and 3 units down.
