COURSE 3 LESSON 3-8
ABC has vertices A (1, –3), B (3, 0), and C (4,–2). Graph ABC and its image after a translation to the left 3 units and up 2 units.
Connect the images of the vertices.
Slide each vertex left 3 units and up
2 units.

3. Write a rule to describe the translation of G (–5, 3) to G (–1, –2).
Translations
COURSE 3 LESSON 3-8
Write a rule to describe the translation of G (–5, 3) to
G (–1, –2).
Point G is moved 4 units to the right and
5 units down.
So, the translation adds 4
to the x-coordinate and subtracts 5 from
the y-coordinate.
The rule is (x, y)     (x + 4, y – 5).
