vectors: A = (2, 2), B = (-1, 7), C = (8, 9); find vector D

[JAsh]

this is kind of easy, but i really cant remember

Position vector A = (2 2)
Position vector B = (-1 7)
Position vector C = (8 9)

The position victor of D is (d 4).
Find d.

What is the point of vectors A, B, and C? (The vector D is not given as being related in any manner to them.)

What information is given about D? (With only the given information, I see no possible way to justify any particular value for "d".)

Thank you!

Eliz.
