Lesson Summary:

In this lesson, you will learn how to write a linear equation using two points and the point slope formula. You will be shown how to calculate the slope of the line and how to plug it into the formula along with one of the points to find the equation of the line. Whether you choose to use the point slope method or the slope-intercept method, finding the slope of the line is the most important step in writing the equation.

Lesson Description:

How to write an equation given two points using point slope formula

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 a linear equation in point-slope form given two points. This is then changed into slope-intercept form. All steps involved in writing the equation are shown and explained.
