Question

The perpendicular distance of the point (2,4,-1) from line $\frac{x + 5}{1} = \frac{y + 3}{4} = \frac{z - 6}{- 9}$ is

Moderate

Solution

$A = (2, 4, - 1)$ ,
Any point on the line $P = (t - 5, 4 t - 3, - 9 t + 6)$
Let P be the foot of the perpendicular of A
AP is perpendicular to given line.
Use formula $a_{1} a_{2} + b_{1} b_{2} + c_{1} c_{2} = 0$ , t = 1
point P(-4,1,-3)
find distance between PandA
