Okay, now why is m slope?
I'd also wondered why r is the correlation coefficient but it turns out it's the "regression" coefficient, as in how strong the regression to the mean is.
- fuzzfactor 2y agoKind of reminds me of a mountain you're going to climb :)
- madcaptenor 2y agoFrom a bit of googling I see some people say it's from French "monter", meaning to climb, which does come from the same root as English "mountain".
- JdeBP 2y agoA lot of these conventions just develop according to what notation sticks, like how π caught on almost 3 millennia after the ratio was treated as a constant. And not all of them are even as universal as one might think. mx+c is not. Charles Hutton used y = ax + b for the equation of a "right line" in xyr 1811 A Course of Mathematics, for example.
- seba_dos1 2y agoI used y = ax + b all the time in school. This is the first time I encounter mx + c.
- anthk 2y agoFor a Basque speaker as me, m was ideal because malda in Basque means... slope :)
- Keyframe 2y agoOkay, now why is m slope? the great divide between US and Europe :D should be a - a, b, c, d... why m though, indeed?
- kqr 2y agoWait, is m slope? I learned it with k (for coefficient) for the slope, and m for the intercept (I don't know why m in that case though).
