As a subject matter expert in mathematics, I can explain that the "M" in the term "slope" stands for "M" in the slope formula, which is typically written as "M = R/S". This formula represents the ratio of the vertical change (Rise) to the horizontal change (Run) between two points on a line. The term "slope" is often used to describe the steepness or incline of a line, and it's a fundamental concept in algebra and geometry.

It is not known why the letter m was chosen for slope; the choice may have been arbitrary. John Conway has suggested m could stand for "modulus of slope." One high school algebra textbook says the reason for m is unknown, but remarks that it is interesting that the French word for "to climb" is monter.read more >>
