Question

The line joining the points $( - 2,1 , - 8 )$ and $( a , b , c )$ is parallel to the line whose direction ratios are 6, 2, 3. The values of $a , b , c$ are

• A. 4, 3, –5
• B. 1, 2, –13/2
• C. 10, 5, –2
• D. None of these

Answer 1

Answer: (A)

4, 3, –5

Answer 2

According to question, $\frac { a + 2 } { 6 } = \frac { b - 1 } { 2 } = \frac { c + 8 } { 3 }$

$\Rightarrow a = 4 , b = 3 , c = - 5$.
