Multiple Choice

Solve the problem.
-Find the vector equation of the line through $A$ and $B$ .
$$A = ( 7,6 , - 7 ) , B = ( 1 , - 3 , - 9 ) , C = ( 6 , - 8,7 )$$

A) $\mathrm { r } = \langle 7,6 , - 7 \rangle - \mathrm { t } \langle 6,9,2 \rangle$
B) $\mathrm { r } = \langle 7,6 , - 7 \rangle + t \langle - 6 , - 9 , - 2 \rangle$
C) $\mathrm { r } = \langle 6,9,2 \rangle + \mathrm { t } \langle 7,6 , - 7 \rangle$
D) $r = \langle 7,6 , - 7 \rangle - t \langle - 6 , - 9 , - 2 \rangle$
