Determine Whether Any of the Lines Given Below Are Parallel

question 111

Multiple Choice

Determine whether any of the lines given below are parallel or identical. $\begin{array} { l } L _ { 1 } : \frac { x - 4 } { 3 } = \frac { y - 9 } { 7 } = \frac { z - 3 } { 2 } \\L _ { 2 } : \frac { x - 3 } { - 3 } = \frac { y - 10 } { - 7 } = \frac { z - 4 } { 2 } \\L _ { 3 } : \frac { x } { 3 } = \frac { y - 2 } { - 7 } = \frac { z - 1 } { - 2 }\end{array}$
$L _ { 4 } : \frac { x - 3 } { 3 } = \frac { y - 10 } { 7 } = \frac { z - 4 } { - 2 }$

• A) \(L _ { 1 } , L _ { 4 }\) are parallel
• B) \(L _ { 2 } , L _ { 4 }\) are identical
• C) \(L _ { 1 } , L _ { 2 } , L _ { 4 }\) are parallel
• D) \(L _ { 1 } , L _ { 2 }\) are identical
• E) \(L _ { 1 } , L _ { 3 }\) are parallel
