# How do you find an ordered pair to represent -8u given u=<-1,4> and v=<3,-2>?

$- 8 \vec{u} = < 8 , - 32 >$

#### Explanation:

We're given two vectors

$\vec{u} = < - 1 , 4 >$

$\vec{v} = < 3 , - 2 >$

and asked to find the value of $- 8 \vec{u}$, so vector $\vec{v}$ I'm assuming is irrelevant..

Vector $\vec{u}$ multiplied by the scalar quantity $- 8$ is thus

$< - 8 \left(- 1\right) , - 8 \left(4\right) >$

= color(blue)(ulbar(|stackrel(" ")(" "<8, -32>" ")|)
