In the xy-plane, what is the slope of line l?

(1) Line l dose not intersect the line with equation y = 1 - x.
(2) Line l intersects the line with equation y = x – 1.


Does it mean that from1- line l is parallel to given line, hence same slope?

if two lines do not intersect then they are must parallel and their slopes are equal.

Yes, if the lines do not intersect in the xy-plane, then they are parallel and have the same slope. So, (1) is sufficient: slope of L=-1 and (2) is not as there are infinite # of lines which intersects the line y=x-1.

Answer: A.
