In this lesson, the instructor teaches how to find the slope of a line graph using two points from the graph. The instructor explains how to determine the coordinate points of the line and how to use these points to create a slope triangle. The video shows how to visually count the length between the two points and how to find the length of the line mathematically. The lesson concludes by showing how to determine the slope of the line by dividing the change in the y-axis by the change in the x-axis.
Find the slope of a line given two points on a graph
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
