In this lesson, you'll learn how to write an equation for a line given its slope and y-intercept. The standard form of a linear equation is y equals mx plus b, where the slope is always in front of the x and the y-intercept is a constant. To graph the equation, plot the y-intercept and use the slope to create a slope triangle. By simply plugging the slope and y-intercept into the equation, you can easily write the equation for any given line.
Write an equation given the slope and y intercept
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.
