10.8 Exercise 30

Determine whether the two vectors $u$ and $v$ are equal, where $u$ has an initial point $P_{1}$ and a terminal point $P_{2}$ and $v$ has an initial point $P_{3}$ and a terminal point $P_{4}$.

$P_{1} = \left(5 , 1\right) , P_{2} = \left(3 , - 2\right) , P_{3} = \left(- 1 , 3\right) ,$ and $P_{4} = \left(9 , - 4\right)$
