A translation and its magnitude

A translation maps \(A(-2,4)\) to \(B(4,-4)\). Each coordinate unit represents 1 cm.

1. Write the translation vector as a column vector.[1]
2. Find the distance from \(A\) to \(B\).[2]
3. The same translation maps \(C(3,-1)\) to \(D\). Find the coordinates of \(D\).[1]
