Exploring the Concept of Slope: Rise Over Run

The video tutorial explains the concept of slope, which measures the steepness of a line. It covers different types of slopes: positive, negative, zero, and undefined. The slope is calculated as the ratio of vertical change (rise) to horizontal change (run). Examples are provided to illustrate positive and negative slopes, emphasizing that a greater slope indicates a steeper line. The tutorial concludes with a summary of the key points about slope and steepness.

What is the primary use of slope in geometry?

• To calculate the area under a line

• To find the midpoint of a line

• To measure the steepness of a line

• To measure the length of a line
