What are you doing to an object when you translate it?
Sliding it

When there is no direction listed, which way do we assume to rotate?

Suppose you do not have a coordinate grid. When translating a shape by a given vector, how can you know for sure you put each point in the right spot?
The line from the point on the pre-image to the point on the image will be parallel to the vector.
