This document contains the equations of 6 sets of lines. Each set contains 2 lines with their respective slope-intercept forms. The slopes and y-intercepts of the lines in each set are provided. The document concludes that if the lines in any set are intersecting, non-parallel lines, then the product of their slopes will not equal -1.
