Understanding y = mx + b
In this lesson, the concept of y = mx + b is explained through the use of graphing and table values. The y-intercept, or b, is identified as the constant number in the equation and is represented on the graph where the line intersects with the y-axis. The slope, or m, is identified as the number in front of x in the equation and is seen as the steepness of the line on the graph. By understanding these two components, one can easily determine the equation of a line and graph it accordingly.
Understand what b and m are in the equation y = mx+b
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.

Staff Review
This lesson starts with a review of graphing lines from a table of values, then it goes into teaching how to understand y=mx+b.
