Answer
$\frac{1}{2}V=(1,2)$
$-V=(-2,-4)$
$4V=(8,16)$
Work Step by Step
Remember to use the coefficients before I and J
after that it should look like this below
$V=(2,4)$
$\frac{1}{2}V=(\frac{1}{2}(a),\frac{1}{2}(b))$
$\frac{1}{2}V=(1,2)$
$-V=(-a,-b)$
$-V=(-2,-4)$
$-V=(-2,-4)$
$4V=(4(a),4(b))$
$4V=(4(2),4(4))$
$4V=(8,16)$
