Chapter 6 Lesson 4 – Graphing Lines Using Slope Intercept Method

Ok, welcome to lesson 4.  This lesson will teach you how to graph a line using the slope-intercept method.  By far this is the most common way students graph lines in algebra so you want to take good notes.  Also, pay extra attention on how we use the slope to plot a line using this method. As you work toward passing the GED you want to stay focused on building up all these math skills we study- everything is important.

Things to focus on in this lesson:

• y = mx + b  format and what m and b represent
• the steps to graph a line in y = mx + b form
• negative and positive slope

Pop quiz: A negative number x a negative number is positive?

Good work you finished lesson 4. You should be able to:

* graph a line in y = mx + b form

* find the slope of a line

* graph one and two variable lines

The next lesson will teach you another method for graphing lines using the x and y intercepts.

Hello John, I am writing to thank you. During the Summer I took and passed all of my GED courses with the exception of the Math test. I found your free math course online and listened and watched all of the videos, trying to educate myself utilizing the tools and tips that you provided. I have to admit, it was very overwhelming and at times I felt as though I was being taught in a foreign language. I scheduled my re-test earlier this week and I passed. Thank you from the bottom of my heart. It took me 22 years to feel confident enough to achieve this goal and I am forever grateful to you for offering this information online. You are heaven sent! Now I can apply for better paying jobs and attend college. Thank you, thank you, thank you for helping others change their lives for the better!!” Sincerely, Alicia
