Formula

slope = (y2 - y1) / (x2 - x1)

Slope compares vertical change to horizontal change between two points.

A vertical line has undefined slope because the run is zero.

Example

2, 3, 8, 11 gives Slope 1. 3333.

Check

Mixing units or scales across x1, y1, x2, y2 before calculating slope.
Rounding too early when the slope still feeds another step.
