The equation of line through the point \( (2,-1,3) \) and
\( \mathrm{P} \)
which is equally inclined to axis
(1) \( \frac{x-2}{-\frac{1}{\sqrt{3}}}=\frac{y+1}{\frac{1}{\sqrt{3}}}=\frac{z-3}{\frac{1}{\sqrt{3}}} \)
(2) \( \frac{x-2}{-1}=\frac{y+1}{1}=\frac{z-3}{-1} \)
(3) \( \frac{x-2}{-1}=\frac{y+1}{-1}=\frac{z-3}{1} \)
(4) \( \frac{x-2}{\sqrt{3}}=\frac{y+1}{\sqrt{3}}=\frac{z-3}{\sqrt{3}} \)
