Video by Julie Harland http://yourmathgal.com This is part 10 of a series of videos about graphing lines. This is a continuation of the ideas presented in part 9, and continues to cover the basic idea of slope, what it means, and how you can determine the slope by looking at a graph. More examples are included.<br />For more great math videos visit: www.youtube.com/user/videosbyjulieharland/videos<br />Aligned to Common Core State Standard: 8.EE.6

Graphing Lines Part 10
Standards
Use similar triangles to explain why the slope 𝑚 is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation 𝑦 = 𝑚𝑥 for a line through the origin and the equation 𝑦 = 𝑚𝑥 + 𝑏 for a line intercepting the vertical axis at 𝑏.
