SUMMARY

The letter "m" is conventionally used to represent slope in mathematical equations, primarily due to historical usage rather than a specific reason. In mathematical notation, letters towards the end of the alphabet, such as x, y, and z, are typically reserved for variables, while letters earlier in the alphabet, like m, are used for parameters. This convention has been widely adopted in educational materials and mathematical literature. For further exploration, a resource detailing the derivation of the "m" in slope equations is available at Duke University's website.

Why is the letter m used to represent slope?

I would rather S for slope.

There's not really any reason, it's just that letters towards the end of the alphabet (x, y, z, w, etc) are usually used for variables while letters away from the end are usually used for parameters.
