The equation of perpendicular from the point (1, 0, 1) to the plane x - y + z = 4 is

$\frac{x-1}{1}=\frac{y}{-1}=\frac{z-1}{1}$

The correct answer is Option (3) → $\frac{x-1}{1}=\frac{y}{-1}=\frac{z-1}{1}$

Point: $P(1, 0, 1)$

plane: $x - y + z = 4$

Normal vector = $\hat i-\hat j+\hat k=\vec n$

so line is perpendicular to plane in direction of $\vec n$ and passes through P

line: $\frac{x-1}{1}=\frac{y}{-1}=\frac{z-1}{1}$
