Writing the Equation of a Line Through Two Points
In this lesson, you will learn how to find the equation of a line given two points. The teacher first explains a visual approach and then demonstrates how to use algebraic methods. The slope formula is used to find the slope, which is then used to calculate the y-intercept. The final equation is written in the form y=mx+b, where m is the slope and b is the y-intercept.
How to find the equation of a line given two points
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.
