Prove That $\overrightarrow{R S}$ And $\overrightarrow{O P}$ Are Equivalent by Showing That They Represent the Same Vector

Prove that $\overrightarrow{R S}$ and $\overrightarrow{O P}$ are equivalent by showing that they represent the same vector.
-R = (4, 5), S = (8, 8), O = (5, 6), and P = (9, 9)
