Answer:
Line m is not parallel to Line n.
Line m is perpendicular to Line k
Step-by-step explanation:
1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel
2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m
