Where does the 'm' come from in y=mx+c

In y=mx+c, I  know that 'm' stands for the gradient of the straight line and the 'c' stands for the y intercept, but why 'm' and 'c'???

I have heard it suggested that 'm' stands for something like 'midron' (meaning gradient) in Hebrew but ?????

And the 'c' .... interCept ??

Any suggestions??

Welcome to MathsIsFun, mgca. However, this is the wrong place to discuss this...

Moveded.

As for the question, I'm afraid I have no idea. It's possible that it doesn't come from anywhere, and they just called it m because they had to call it something.


Why did the vector cross the road?
It wanted to be normal.

m may be connected with "multiply" or something
And c is something as constant-it is used very much in calculus it means a free-of-unknowns addend, i think.

The m comes from MathIsFun.
