Using a slope triangle to find the slope on a graph - Math teacher shows test answers

The video tutorial explains how to find the slope of a line by identifying coordinate points and calculating the change in Y values over the change in X values. It covers both visual and algebraic methods, including using slope triangles and subtraction to determine the slope. The tutorial emphasizes the importance of consistent order in subtraction and provides examples to illustrate the concepts.

What does the change in Y values over the change in X values represent?

How can you find the slope if the slope triangle method is difficult to apply?
