What are the coordinates of its image, B ? Graph B . and 2 units to the left of point B. Count down 5 units from point B The coordinates of B are (0, –6). 3-8

Connect the images of the vertices. Translations 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. 3-8

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). 3-8
