At about the 1:37 mark, the teacher gets a 3 for what is inside the parentheses; he should get a 4. Therefore, m=-3.

Lesson Summary:

In this lesson, you'll learn how to find the slope between two points. Using the point slope formula, which states y2 minus y1 equals m times x2 minus x1, you'll discover how to plug in the values and label the x and y coordinates. Once this is done, you can find the value of m or the slope. The slope formula, which is much easier to use, states that m equals y2 minus y1 all over x2 minus x1. By simply plugging in the values and reducing, you can find the slope with ease.

Lesson Description:

Given two points find the slope

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.
