Determining negative slope from a graph

The video tutorial explains how to determine the slope from a graph. It begins with an introduction to the concept of slope and the importance of finding two coordinate points. The instructor then demonstrates how to use a slope triangle to calculate the slope, emphasizing the creation of a right triangle. The tutorial includes a detailed step-by-step calculation of the slope using given coordinates, highlighting common mistakes and how to correct them. The final result is a negative slope of -2/7, with a reminder to ensure consistent direction when reading points.
