There is a really easy way to do this problem and that is to use a graphing website

after punching in the functions:

A. depending of whether it is -5/(2x) or (-5/2)x: intersecting but not perpendicular or parallel
B. These two lines are perpendicular
C. Parallel lines
D. intersecting but not perpendicular
