Warm up 1.Write the rule for translating left 4 units and up 6 units. 2.Write the rule for reflecting over the x-axis. 3.Write the rule for reflecting over the line y=x. 4.Write the rule for reflecting over the y-axis. 5.Write the rule for reflecting over the line y=-x.

2
Warmup The table below shows the number of people per 100,000 that were unemployed in the state of Georgia the selected years. a) Find the regression equation appropriate for this data set. Round values to two decimal places. Let x = 0 correspond to Y=-25.95x + 569

3
Rotations

4
Rotations A rotation is a ________ around a center. The _______________ from the center to any point on the shape stays the ___________. turn distance same

5
Rotate 90 Clockwise about the Origin Change the sign of x and switch the order

6
Rotate 90° clockwise about the origin

7

8
Rotate 90° counterclockwise about the origin

9
E F G

10
Rotate 90 Counterclockwise about the Origin (Same as 270 Clockwise)

11
Rotate 90° counterclockwise about the origin E F G Get the points of where they should be….then graph them! E F G 90° CW 180° CW E F G 270° CW

12
Rotate 90° counterclockwise about the origin Change the sign of y and switch the order E F G

13
Rotate 270 Clockwise about the Origin Change the sign of y and switch the order

14
Rotate 270° clockwise about the origin

15

16
Rotate 270 Counterclockwise about the Origin (Same as 90 Clockwise) Change the sign of x and switch the order

17
Rotate 270° Counterclockwise about the origin

18
A B C

19
Get the points of where they should be….then graph them! A’ B’ C’ 90° CW

20
Rotate 270° Counterclockwise about the origin A B C

21
Rotate 180 about the Origin ONLY Change the signs

22
Rotate 180° about the origin

23
Q R S

24
Q R S Get the points of where they should be….then graph them! 90° CW Q R S 180° CW
