Question:
Use the image to answer the question.
A rectangle $ABDC$ has vertex $A$ at $(-5, 4)$ and vertex $B$ at $(-1, 4)$.
After applying a translation vector to rectangle $ABDC$, the coordinates of $A'$ are $(-6, 8)$. What are the coordinates of $B'$?

Answer 1

Translation vector = A' - A = (-6 - (-5), 8 - 4) = (-1, 4).
So B' = B + (-1,4) = (-1-1, 4+4) = (-2, 8).
