उत्तर

The direction ratios of the line parallel to line  \[\frac{x - 3}{4} = \frac{y - 5}{2} = \frac{z + 1}{3}\] are proportional to 4, 2, 3.


Equation of the required line passing through the point (1, 2,-4) having direction ratios proportional to 4, 2, 3 is

\[\frac{x - 1}{4} = \frac{y - 2}{2} = \frac{z - \left( - 4 \right)}{3}\]

\[ = \frac{x - 1}{4} = \frac{y - 2}{2} = \frac{z + 4}{3}\]
