It turns out there is not a simple answer. Math Forum, an authoritative website from Drexel Univ. posts the following answer:

Why call slope m has been a question that has been researched by

math historians but has not been answered definitively yet. All the

usual suggested “reasons” have proven false. One math historian has

been doing a search for a few years for the earliest use in a math book.

So the jury is still out on this question.
