The initial and terminal points of vector v are (3,-8)and (7,1),respectively.Select v in component form. ?
A)? $\mathbf { v } = \langle - 4 , - 9 \rangle$
B)? $\mathbf { v } = \langle - 4,9 \rangle$
C) $\mathbf { v } = \langle 4,9 \rangle$
D) $\mathbf { v } = \langle 4 , - 9 \rangle$
E)? $\mathbf { v } = \langle 9,4 \rangle$

Question

Quizplus · Accepted Answer

The component form of a vector is found by subtracting the coordinates of the initial point from the coordinates of the terminal point. Thus, $v = \langle 7 - 3, 1 - (-8) \rangle = \langle 4, 9 \rangle$.

The Initial and Terminal Points of Vector V Are (3,-8)and v=⟨−4,−9⟩\mathbf { v } = \langle - 4 , - 9 \ranglev=⟨−4,−9⟩
