Determining undefined slope between two points

The video tutorial explains how to determine the slope between two points, especially when the X coordinates are the same. It highlights the importance of understanding that no horizontal change results in a vertical line, leading to an undefined slope. The tutorial applies the slope formula to demonstrate this concept, showing that a zero in the denominator indicates an undefined slope. The video concludes by reinforcing the idea that unchanged X values create a vertical line with an undefined slope.
