Lesson Summary:

In this lesson, you will learn how to find the equation of a line using the point slope method. Using the given two points, the teacher shows how to solve for the slope using the point slope form. The teacher then demonstrates how to find the equation of the line using the slope and one of the given points. By the end of the lesson, you will have the knowledge to find the equation of a line given two points in a simplified and understandable way.

Lesson Description:

How to find the equation of a line given two points using the point slope method

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.

    This lesson will show you how to find the slope between two points and then how to write the equation in point-slope form for a line given two points. This is then changed into slope-intercept form. All steps involved in writing the equation are shown and explained.
