The video tutorial explains the concept of undefined slope, which is associated with vertical lines. It describes how vertical lines run up and down, not left to right, and have a zero in the denominator of the slope formula, making the slope undefined. The tutorial also covers how ordered pairs for vertical lines have the same x-values but different y-values. An example is provided to illustrate this, and the slope formula is used to demonstrate why the slope is undefined for vertical lines.

What is the main characteristic of a vertical line?

• It goes left to right.

• It goes up and down.
