# Find the value of p, so that the lines and are perpendicular to each other. Also find the equations of a line passing through a point (3, 2, –4) and parallel to line l_{1}.

Answer :

Given:

The equation of line can be rewritten as:

Vector form of L_{1}:

Vector form of L_{2} :

P = 7 …(1)

Now let the line passing through point (3,2,-4) and parallel to L_{1} be L’.

(as L' is parallel to L_{1} and we can neglect the constant v

because it is deciding magnitude only.)
