Question 120

Multiple Choice

Let w\mathbf { w } be a vector with initial point (2,1) ( 2,1 ) and terminal point (9,3) ( 9 , - 3 ) . Write w\mathbf { w } as a linear combination of the standard unit vectors i\mathbf { i } and j\mathbf { j } .


A) w=i+12j\mathbf { w } = \mathbf { i } + 12 \mathbf { j }
B) w=5i+8j\mathbf { w } = - 5 \mathbf { i } + 8 \mathbf { j }
C) w=7i4j\mathbf { w } = 7 \mathbf { i } - 4 \mathbf { j }
D) w=11i+4j\mathbf { w } = 11 \mathbf { i } + 4 \mathbf { j }
E) w=3i12j\mathbf { w } = 3 \mathbf { i } - 12 \mathbf { j }
