Hello, Please I have done a homework and it says my last answer is wrong please help. Thanks. I believe line L2 and L3 are skew but the distance I gave isn't correct.
> Given two lines in space, either they are parallel, they intersect, or they are skew (lie in parallel planes). Determine whether the lines below, taken two at a time, are parallel, intersect, or are skew. If they intersect, find the point of intersection. Otherwise, find the distance between the two lines. L1: x = -1+1, y = -1+2t, z=-1-t, -∞<t<∞ L2: x= 4+2s, y = 11+ 4s, z=1-2s, -∞o<S<∞ L3: x = -1+r, y = -1+4r, z=-1-2r, -∞<r<∞ D c. L1 and L2 intersect at the point (.). Select the correct choice below and fill in the answer box(es) to complete your choice. (Type exact answers, using radicals as needed.) OA. L1 and L3 are parallel. Their distance is OB. L1 and L3 are skew. Their distance is Incorrect: C. L1 and L3 intersect at the point (-1,-1,-1). Select the correct choice below and fill in the answer box(es) to complete your choice.
