Multiple Choice

The symmetric equations of the line through (3,2,1) in the direction of $3 \mathbf { i } - \mathbf { j } + \mathbf { k }$ is

A) $\frac { x - 3 } { 3 } = \frac { y - 2 } { - 1 } = \frac { z - 1 } { 1 }$
B) $\frac { x - 3 } { - 3 } = \frac { y - 2 } { 1 } = \frac { z - 1 } { - 1 }$
C) $\frac { x - 3 } { - 3 } = \frac { y - 2 } { - 1 } = \frac { z - 1 } { 1 }$
D) $\frac { x + 3 } { 3 } = \frac { y - 2 } { - 1 } = \frac { z - 1 } { - 1 }$
E) $\frac { x - 3 } { - 3 } = \frac { y - 2 } { - 1 } = \frac { z + 1 } { - 1 }$
