1.2 Review Worksheet (continued)
20. A figure has vertices at J ( − 2, 3), K (0, 3), L (0, 1), and M ( − 2, l). After a transformation, the image of the figure has vertices at J ′(2, 1), K ′(4, 1), L ′(4, − 1), and M ′(2, − 1). Draw the preimage and image. Then identify the transformation.
21. The coordinates of the vertices of rectangle ABCD are A ( − 4, 1), B (1, 1), C (1, − 2), and D ( − 4, − 2). Find the coordinates for the image of rectangle ABCD after the translation ( x , y ) → ( x + 3, y − 2). Draw the preimage and the image.
22. Write a rule for the translation that maps the descent of the hot air balloon.
