Find 3 different explanations why we use m to symbolize slope.

I did the same quiz i know the right answer 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.

hope i could help
