Writing Equations of Lines in Algebra

This clip is just a few minutes of a multi-hour course.  
Master this subject with our full length step-by-step lessons!



Lesson Summary:
In this lesson, you'll learn how to write the equation of a line in algebra when you are given or can find the slope of the line along with the y-intercept.  Writing lines in algebra is very importnant because there are many real-world problems that can be described by a simple line.

Many students have problems understanding the concept of the equation of a line, but the concept is very simple once the student can see example problems that are worked step-by-step.  The slope describes how settp the line is, and the y-intercept simply tells us where the line crosses the y-axis.  

These two pieces of information are all that is needed in order to write down the equation that describes all points that fall on the line.
