Exploring the Slope of a Line

The video tutorial covers the concept of slope, explaining it as the vertical change over the horizontal change, or rise over run. It discusses different types of slopes, including positive, negative, zero, and undefined slopes. The tutorial also demonstrates how to calculate slope using the formula (Y2 - Y1) / (X2 - X1) with examples. Additionally, it distinguishes between constant and variable rates of change, emphasizing the importance of understanding these concepts for linear and nonlinear functions.

What is the formula for calculating the slope of a line?

• Sum of vertical and horizontal changes

• Product of vertical and horizontal changes

• Vertical change divided by horizontal change

• Horizontal change divided by vertical change
