Although the teacher says the new y-intercept is negative eleven halves (-11/2), it is actually negative eleven and a half (-11 1/2).

Lesson Summary:

In this lesson, you will learn how to write an equation for a line that is parallel to a given line and passes through a given point. To find the new equation, use the same slope as the given line and plug in the coordinates of the given point to solve for the new y-intercept. By using these steps, you can easily find the equation of a parallel line that passes through a specific point.

How to write an equation for a line parallel to a given line and through a given point

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 explains how to find the slope of a line parallel to another line, and then how to find the y-intercept and write an equation for the new line that passes through a given point. All steps are explained.
