### 9-1: TEKS Practice

• 1. Multiple Representations Which figure is the image of ΔDEF after a translation? Use arrow notation to show how each vertex of ΔDEF maps to its image after the translation. • 2. The coordinates of ΔDEF are D(4, 3), E(7, 3), and F(6, 8). If you translate ΔDEF 4 units left and 3 units up, what are the coordinates of F′?

• 3.

• a. Describe the location of the image of the figure under the given translation relative to the original figure.

open x comma y close rightwards arrow open x plus 3 comma y plus 2 close • A. The image is up and to the left.

• B. The image is up and to the right.

• C. The image is down and to the right.

• D. The image is down and to the left.

• b. Choose the graph that shows the figure and the image under the given translation.
