The answer is 6 units. I’ll give you hints.
Dr’s of the line is ] = 6units2+(5-1)2+(4-0)2Therefore, PN = sqrt[(3-1)
So N = (1,0,1)
Satisfying this point on the plane gives u=-4
General point on this line is..(u/2 +3, u+4, u+5) say N
Eq. of the line passing through given point P(3,4,5) with these Dr’s (x-3)/1/2 = (y-4)/1 = (z-5)/1
Dr’s of the line is ] = 6units2+(5-1)2+(4-0)2Therefore, PN = sqrt[(3-1)
So N = (1,0,1)

Eq. of the line passing through given point P(3,4,5) with these Dr’s (x-3)/1/2=(y-4)/1=(z-5)/1
2+(5-1)2+(4-0)2] = 6units

General point on this line is..(u/2 +3, u+4, u+5) say N
Eq. of the line passing through given point P(3,4,5) with these Dr’s (x-3)/1/2=(y-4)/1=(z-5)/1
2+(5-1)2+(4-0)2] = 6units
