# How do you write the ordered triple that represents TM given T(3,-5,6) and M(-1,1,2)?

$\left(- 4 , 6 , - 4\right)$.
$\vec{T M} =$ the position vector (pv) of $M$--pv. of $P$
$= \left(- 1 , 1 , 2\right) - \left(3 , - 5 , 6\right) = \left(- 1 - 3 , 1 - \left(- 5\right) , 2 - 6\right) = \left(- 4 , 6 , - 4\right)$.
