Who discovered the slope intercept formula y=mx+b?
Any time you have a line, there’s two noticeable aspects to it: (1) The SLOPE. (2) The Y-INTERCEPT. In fact those are the only two aspects to a line on a plane. The slope is most simply expressed as change in Y for a change in X. The Y intecept is the value of Y when X = 0. It’s not too hard to go from there to the formula that incorporates these two parameters.
