I am an eighth grade teacher and was discussing slope with my Algebra I class and one of my students asked, "Why did they chose the letter m to represent slope? Why not s or another variable?" I know that s is referred to as distance in other mathematics, but why m? I have searched and all I can find is the explanation on how to derive slope, not why that specific variable was chosen. Does anyone know the answer? Please e-mail me the answer if you know why. My kids and I would really appreciate it! Also, if you know of a source I could use, please include that as well. Thanks in advance for your help!
