1. Warm Up:
How do you think you did on the test? Was it easy? Hard? Why do you think so?
Write a function rule to describe each of the following
Translation one unit left and four units down
Translation 6 units up
Translation 4 units right, 11 units down
HINT: (x , y)  ( , )

2. Unit 3 - Transformations Lesson 17.1 Dilations

4. They’re half the size that they were in layout A
(x,y)  ( 𝟏 𝟐 x, 𝟏 𝟐 y)

6. They’re 2 times bigger than they were in layout A.
(x,y)  (2x,2y)

7. RECALL:
preimage: initial figure
Image: new figure

8. 𝟎< 𝒌 <𝟏
𝒌 >𝟏
Multiply each coordinate by k
(x,y)  (kx,ky)

9. 1) Translation: subtract 4 from each x, subtract 6 from each y
2) Dilation: multiply each coordinate by ½

12. Homework: 247 # 26, 28 – 31 * Do on graph paper (if possible) *
Do on the sheet of graph paper that I gave to you.
Clearly label each problem
You must attempt every problem for full credit.
Whatever isn’t finished is homework.
