Determining positive slope from a graph positive

The video tutorial explains how to find the slope of a graph using slope triangles. It begins by introducing the concept of slope triangles and the importance of using horizontal and vertical lines to create right triangles. The instructor demonstrates how to calculate the change in Y and X coordinates to determine the slope, emphasizing the positive direction of the graph. The tutorial provides a step-by-step guide to creating slope triangles and finding the slope from a graph.

What coordinates were used in the example to create the slope triangles?

Describe the process of finding the slope from the graph as mentioned in the text.
