Choose:
 (3,11) (5,11) (5,1) (6,1) 2.
Which translation mapping is depicted in the graph at the right?

Choose:
 (x, y) → (x + 6, y - 3) (x, y) → (x - 3, y + 6) (x, y) → (x - 6, y + 3) (x, y) → (x + 3, y - 6) 3.

a) What are the coordinates of A ?
b) What are the coordinates of P' ?
c) Write the translation function that was used in this design.

The diagram at the right shows 16 dots from a sheet of dot paper, where the dots are equally spaced. A translation maps dot B to dot K.
Under this translation to which dot will dot E be mapped?

Choose:
 C J O N 10 Explain why there can be no "fixed" points under a translation, other than the translation T0,0.
