Lesson Summary:

In this lesson, students learn about the different forms of writing lines, including point-slope and standard forms. They also learn how to convert between forms and how to graph lines using these forms. The lesson provides step-by-step instructions on finding equations given a point and a slope or two points. It also covers what to do when dealing with vertical and horizontal lines. Overall, the lesson provides a thorough understanding of writing and graphing equations for lines.

Lesson Description:

An explanation of point-slope and standard forms for lines. Also, an explanation of how to get to point-slope form from slope intercept form. How to write equations for equations given a point and a slope or two points, and changing between forms of lines. Finally, graphing lines from the three different forms.
