  1. More Transformations (Here are the notes for the three examples)

  2. First, graph the points Ex 1:

  3. Ex 1: Next, translate 2 to the left

  4. Now, reflect about the y-axis Ex 1:

  5. Now to dilate by a scale factor of ½ about the point ( -2 , 0 ). Basically, imagine a nail keeping the point ( -2 , 0 ) in place, and scaling everything by ½ about that reference point.

  6. Finally, dilate about (-2 , 0) Ex 1: B B’ I O I’ O’

  7. Final Answer: O’(-1.5,0) B’(-1.5,2) I’(-2.5,0) Ex 1: B B’ I O I’ O’

  8. Now for Example 2:

  9. First, graph the points Ex 2: B I O

  10. Rotate 180 about the origin Ex 2: B I O

  11. Rotate 180 about the origin Ex 2: B I O

  12. Rotate 180 about the origin Ex 2: B I O

  13. Rotate 180 about the origin Ex 2: B I O

  14. Rotate 180 about the origin Ex 2: B I O

  15. Rotate 180 about the origin Ex 2: B I O

  16. Translation 4 units up Ex 2: B I O

  17. Ex 2: Dilation of scale factor of ½ about the origin. B O’ I’ B’ I O

  18. Final Answer: O’(-1.5,2) B’(-1.5,0) I’(-2.5,2) Ex 2: B O’ I’ B’ I O

  19. Now for Example 3:
