Moderate# Reflections and Translations

ACTMAT-OKT1L4

$ {\Delta} $ ABC is reflected about the line $x = 2$ to form $ {\Delta} $ A'B'C'.

$ {\Delta} $A'B'C' is then reflected about the line $x = -1$ to form $ {\Delta} $ A"B"C". The mapping from $ {\Delta} $ ABC to $ {\Delta} $ A"B"C" is also obtained by a translation.

If the coordinates of $ {\Delta} $ ABC are A$(0,2)$, B$(3,5)$, and C$(6,-1)$, which of the following describes the translation mapping from $ {\Delta} $ ABC to $ {\Delta} $ A"B"C"?
