What does it mean when the slope is undefined?
Space and AstronomyThe undefined slope is the slope of a vertical line. The x-coordinates do not change, no matter what y coordinates are. The vertical lines rise straight up or fall straight down, whereas they don’t run left or right. The slope is the ratio of the change in y coordinates to the change in x coordinates.
