If I have two points in positive cartesian coordinates, how do I find:
- The slope of a line between those points
- The increment amount to get from $(x_1, y_1)$ to $(x_2, y_2)$ one dot at a time.
What I know so far is $m=\frac{y_2-y_1}{x_2-x_1}$
But that gives me a single number, I need a pair of numbers I can add to $x$ and $y$ over the course of a series of iterations to reach $(x_2,y_2)$.
Thanks
