Question:medium

The image of a point \( P(3,5,3) \) in the line \( \frac{x}{1}=\frac{y-1}{2}=\frac{z-2}{3} \) is \( P'(a,b,c) \). Then \( a+b+c = \)

Show Hint

For reflection in a line (3D), use midpoint concept and parametric form of lineIt simplifies calculation instead of vector projection method.
