Practice Test 11

On a coordinate plane, a vector $\mathbf{v}$ is drawn from the origin to $(4,6)$. Where does $1.5\mathbf{v}$ terminate?

For vector $\mathbf{v}=\langle 2,1\rangle$, what is the effect of multiplying $\mathbf{v}$ by $k=-2$ on its length and direction (as it would appear on a coordinate plane)?
