the shorter side of similar right triangles

Reason: given any two segments of the same line you can form right triangles with the horizontal (or vertical). Those right triangles share an acute angle, so they are similar; therefore their corresponding legs are proportional. The slope (rise/run) is the ratio of the vertical leg to the horizontal leg, so that ratio is the same for both triangles, hence the slope is the same between any two points on the line.
