Answer 1

1)C×(-2/3)
-2/3c
2)D×3 7/9
D×34/9
34/9D

Answer 2

It appears that you provided coordinates for two points: C and D. Let's clarify the coordinates for each point:

1. Point C: (x, y) = (-2/3, y)
2. Point D: (x, y) = (-3 7/9, y)

To make it clear, I'll represent the second point, D, in decimal form:

1. Point C: (x, y) = (-2/3, y)
2. Point D: (x, y) = (-3.777..., y) (rounded to three decimal places)

If you have any specific questions or tasks related to these points, feel free to let me know!
