- Help me pleasearrow_forwardLet L₁ be the line passing through the points Q₁=(−1, −3, 1) and Q₂=(−4, −6, 2). Find a value of k so the line L₂ passing through the point P₁ = P₁(−14, 12, k) with direction vector d=[-2, 6, −5]ª intersects with L₁. k = 0arrow_forwardQ1. Show that the vectors x, =(1,2,4), x, = (2,-1,3), x, = (0,1,2) and x, =(-3,7,2) are linearly dependent and find the relation between them. Ans: 9x, - 12x, + 5х, - 5х, -0 Q2. If the vectors (0,1,a), (1, a,1) and (a,1,0) is linearly dependent, then find the value of a. Ans: 0,+/2 Q3.
