Two lines with the same slope are parallel

Question

this is a question on my algebra class I need help with

Answer 1

two lines with the same slope are parallel

that's basically true same slope=parallel

Unless they are one and the same identical line. Then it's a matter of convention Not to describe itself as parallel to itself

two lines with different slopes are Not parallel

two lines that are Not parallel have different slopes (except possibly for the degenerate case of two identical lines)
