Question

The direction ratios of the line joining the points (4, 3, –5) and (–2, 1, –8) are

• A. $\frac { 6 } { 7 } , \frac { 2 } { 7 } , \frac { 3 } { 7 }$
• B. $6,2,3$
• C. $2,4 , - 13$
• D. None of these

Answer 1

Answer: (B)

$6,2,3$

Answer 2

Direction ratios are, $l = 4 - ( - 2 ) = 6 , m = 3 - 1 = 2$ and

$n = - 5 + 8 = 3$.
