Question:

The direction ratios of the line \(\dfrac{x+1}{3}=\dfrac{y-2}{3}=\dfrac{z-5}{6}\) are

Show Hint

Denominators in the symmetric equation give the line's d.r.s.
  • \(1,-2,5\)
  • \(3,2,5\)
  • \(3,3,6\)
  • \(1,3,5\)

The Correct Option is C

Solution and Explanation

In the symmetric form \(\dfrac{x-x_{0}}{l}=\dfrac{y-y_{0}}{m}=\dfrac{z-z_{0}}{n}\), the denominators \(l,m,n\) are direction ratios. So d.r.s are \((3,3,6)\).
