Find the slope of a line given graph

The video tutorial explains how to find the slope of a line graph using two methods: coordinate points and the slope triangle method. It begins by identifying coordinate points on the graph, then demonstrates how to calculate the slope using these points. The tutorial also covers the slope triangle method, which involves creating a right triangle on the graph to determine the slope. Both methods are shown to yield the same result, emphasizing the concept of slope as a ratio of vertical to horizontal change.

How do you determine the change in y-coordinates when moving from the origin to the point?
