The vector v has initial position P and terminal point Q. Write v in the form ai + bj; that is, find its position vector.
-P = (4, 4); Q = (-3, -6)
A) v = 10i + 7j
B) v = -7i - 10j
C) v = -10i - 7j
D) v = 7i + 10j

Question

Quizplus · Accepted Answer

The position vector $ \mathbf{v} $ from point P to point Q is found by subtracting the coordinates of P from Q: $ \mathbf{v} = (-3 - 4)i + (-6 - 4)j = -7i - 10j $.

The Vector V Has Initial Position P and Terminal Point
