D. -⅓ sqrt(2)

Step-by-step explanation:

8 = 2²×2

32 = 4²×2

sqrt(2/9) - 3sqrt(2²×2/9) + sqrt(4²×2/9)

sqrt(2/9) - 6sqrt(2/9) + 4sqrt(2/9)

sqrt(2/9) [1 - 6 + 4]

sqrt(2/9)(-1)

9 = 3²

-sqrt(2/3²)

-⅓sqrt(2)

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
