10.8 Exercise 153

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 $P_{4} .$

$P_{1} = \left(6 , 11\right) , P_{2} = \left(- 2 , 8\right) , P_{3} = \left(0 , - 1\right)$ and $P_{4} = \left(- 8 , 2\right)$
