Using slope triangle to find the slope of a graph

The video tutorial explains how to find the slope of a line on a graph. It begins by defining slope as the change in Y values over the change in X values. The instructor introduces the concept of a slope triangle, which helps visualize the change between two points on a graph. By selecting two points, such as (-2, 0) and (0, 4), the instructor demonstrates how to create a right triangle and calculate the slope by determining the rise and run. The slope is calculated as 4/2, which simplifies to 2. The lesson concludes with a brief Q&A session.

What is the slope of a line defined as?

• The change in X values over the change in Y values

• The change in Y values over the change in X values

• The difference between X and Y values

• The sum of X and Y values

What is the first step in creating a slope triangle on a graph?

• Calculating the slope

• Identifying two points on the graph

• Drawing a vertical line

• Drawing a horizontal line

How do you form a right triangle on a graph to find the slope?

• By using diagonal lines

• By using only vertical lines

• By using vertical and horizontal lines
