# Image of the point P with position vector, has the position vector: Option 1) (-9,5,2) Option 2) (9,5,-2) Option 3) (9,-5,-2) Option 4) None

As learnt in

Perpendicular distance of a point from a line, foot of perpendicular and image (Cartesian form ) - - wherein

L be the foot of perpendicular drawn from on the line

Co-ordinates of L will be

DR's of PL will be

PL is perpendicular to line,

Find and put in coordinates of L Distance between P and L is perpendicular distance Image Q can be obtained by applying mid point formula in P and Q and equating it to L obtained.

We have equation of the line in cartesian form:

lie on the given line.

So,

So,

Putting iv (i),

So,

Option 1)

(-9,5,2)

This solution is incorrect

Option 2)

(9,5,-2)

This solution is correct

Option 3)

(9,-5,-2)

This solution is incorrect

Option 4)

None

This solution is incorrect
