Q Draw and label AABC on a coordinate grid. Use these coordinates: A (-4, 5),
B(-5, 1)andC{-2, 2).
Q Translate AABC 6 units to the right and 1 unit down. Label the points in the
image A', B' and C.
Q Write down the coordinates of AA'B'C.

Q AABC is the object that is translated.
AA'B'C is the image formed as a result of the translation.
The coordinates of AABC are: A' (3, 4), B' {2, 0) and C (5, 1).
