A quick end-of-class check. Two tickets print on each page; cut along the dashed line. The answer key prints on its own page after it.

Exit Ticket: Transformations

Grade 8 · CCSS 8.G.A.1

Name

1. Translate (−1, 3) by the rule (x + 5, y − 4).

( )

2. Rotate (2, −3) 90° counterclockwise about the origin.

( )

3. Reflect (−4, 5) over the x-axis. Which coordinate changed, and why?

( )

Answer Key: Exit Ticket

Transformations

(−1 + 5, 3 − 4) → (4, −1)
(−y, x) → (3, 2)
(−4, −5). Only y changes: the point flips to the other side of the x-axis but stays the same distance left of the y-axis.

Quick read: (−3, −2) on #2 is a clockwise rotation (wrong direction); (4, 5) on #3 is a reflection over the wrong axis. Both are named mistakes in the game's Practice mode.
