Part of video series Writing Equations for Lines
Taught by MrA

### Meets NCTM Standards:

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.
• What is point-slope form?
• What is standard form?
• How do you graph using point-slope form?
• How do you graph using standard form?
• How do you change between forms of lines?
• How do you write an equation given a point and a slope?
• How do you write an equation given two points?
Need a quick refresher course on the types of equations you can write for lines? Just need to see some more examples of graphing lines of different forms and changing between forms of lines? This lesson along with the resources will really cement the idea of slope, y-intercept, writing equations for lines, and graphing in your mind. An especially helpful lesson if you are struggling in Algebra.
