Given two points (x1, y1) and (x2, y2), the formula for the slope of the straight line going through these two points is:
Rise/run is the thing to keep in mind. X also stands for the number 1. So, when you rise up one, you will be going over 1 too.
However, if there is no run, the slope will be "undefined". That is just a straight vertical line.
