Determining undefined slope from a table

The video tutorial explains how to determine the slope from a table of values. It highlights that when X coordinates remain constant, the slope is undefined, resulting in a vertical line. The tutorial demonstrates calculating changes in Y and X coordinates and clarifies the concept of undefined slope due to division by zero.

How do you determine the slope when the X coordinates are unchanged?

What is the formula to find the slope using two points?

What happens to the slope when the change in X coordinates is zero?

Explain why the slope is considered undefined when the X values do not change.

What type of line is produced when the slope is undefined?
