Select the correct answer.
if vector u = < 2.5, -4> and vector v= < -2,4> , which graph shows the resulting vector for v - 2u?

A

Step-by-step explanation:

v - 2u

= < - 2, 4 > - 2 < 2.5, - 4 > ← multiply each component by 2

= < - 2, 4 > - < 5, - 8 > ← subtract corresponding components

= < - 2 - 5, 4 + 8 > = < - 7, 12 >

Graph A shows the resulting vector

Graph A

Step-by-step explanation:

Hi, to answer this we have to solve the expression.

u = <2.5, -4>  

v= <-2,4>

v - 2u = <-2,4>- 2<2.5, -4>  

v - 2u = <-2,4>- <5, -8>  

v - 2u = <-7,12>

Correct option is A.

For the graph , we have to move 7 places to the left in the x axis (negative), go up in the y axis by 12 units, and connect that point with the (0,0).

Feel free to ask for more if needed or if you did not understand something.

the answer to the question is a  

it has the same slope and the same y-intercept.
