Answer
$\lt -1,1 \gt$
Work Step by Step
Let us consider $O$ as origin and $P$ as the mid-point of segment $RS$.
The mid-point can be found as: $(\dfrac{x_1+y_1}{2},\dfrac{x_2+y_2}{2})$
$P(\dfrac{x_1+y_1}{2},\dfrac{x_2+y_2}{2})=P(\dfrac{2+(-4)}{2},\dfrac{-1+3}{2})= \lt -1,1 \gt$
$OP=P-O=\lt -1,1 \gt -\lt 0,0 \gt =\lt -1,1 \gt$
Hence, our final answer is: $\lt -1,1 \gt$
