Determining a slope of zero between two points

The video tutorial explains how to apply the slope formula to determine the slope between two points. It begins with an introduction to the formula, followed by labeling the X and Y coordinates. The tutorial then demonstrates the calculation process, highlighting the handling of double negatives. Finally, it explains the concept of horizontal lines and why they result in a slope of zero.

What is the slope formula and how is it applied?

Explain how to find the change in Y coordinates using the slope formula.

How do you label the coordinates when applying the slope formula?

What does it mean when the slope equals zero?

Describe the significance of a horizontal line in relation to slope.
