Application +4 | -1

The line

I_1

passes through the point

(2,6,2)

and is perpendicular to the plane

2 x+y-2 z=10

. Then the shortest distance between the line

h

and the line

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

View answer and explanation

Correct option: C

Option C (9) is correct because it represents the shortest distance between the two lines, calculated using the formula for skew lines.
