I think your answer is distinct parrallel lines. Plz correct me if im wrong but this is because althought there is a negative slope in both of them, and there is the same slope in both of them, there are different points after. For example, after the slope in the first one, you start at 5, in the second one, you start at 4 if you solve the questoon. These are not perpindivular because the slopes are not different
