About This Lesson

Video by Julie Harland This is part 12 of a series of videos about graphing lines. Continuation of the ideas from Graphing 11: More examples showing how to find the slope of a line passing through two points by using the algebraic formula for slope.<br />For more great math videos visit:<br />Aligned to Common Core State Standard: 8.EE.6


Use similar triangles to explain why the slope ? is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation ? = ?? for a line through the origin and the equation ? = ?? + ? for a line intercepting the vertical axis at ?.
