Why is the letter m used for slope instead of s?

[mathdad]

Why is the lower case letter m used to represent slope?

Doesn't it make more sense to use the letter s to represent slope, you know, s for slope?

In Calculus, "s" usually denotes curve length, at least as I am familiar with it. A quick web search fails to turn up any specific reason as to why slope is denoted "m".

I forgot that I had already asked this question back in February 2017.
