Just need answer no need for complex explanation

What is the point of intersection between the lines? : L1: vector r = 3 points (3,7,2) + m( 1, -6, 0) ; m belongs to R &L2: vector r = (-3, 2, 8) + s( 7,-1, -6) ; s belongs to R No POI - Lines are skew O (4, 1, 2) O Infinite solutions - Lines are parallel & coincident O No POI - Lines are parallel & distinct
