HELP ME ANSWER #21 and #22 PLEASEEE THANK YOUUUU

Answer 1

Step-by-step explanation:

21. parallel

22.If two lines in a plane do not intersect, they are parallel. If two lines in space and not in the same plane do not intersect, they are skew. The answer is yes. Two lines can only be non-intersecting if their slopes are exactly the same (otherwise they'd have to cross at some point).

hope this helps you.
