Question

Let L1 be the line passing through the points Q1=Q1(4, −2, −1) and Q2=Q2(3, −3, −4)and let L2 be the line passing through the point P1=P1(−11, 11, 3) with direction vector →d=[−6, 6, 3]T. Determine whether L1 and L2 intersect. If so, find the point of intersection Q. (PS if you could include a step by step and not the answer that would be great!)
