Exploring the Concept of Slope from Two Points

Mr. Han introduces the concept of slope as rise over run and explains how to calculate it using two coordinate points without graphing. He provides step-by-step examples to demonstrate the process, emphasizing the importance of consistent subtraction order. The video concludes with a summary of the method's usefulness, especially for large numbers.

What is the basic concept of slope as introduced in the video?

• Rise over run

• Speed over distance

• Height over width

• Distance over time
