Understanding Slope with Similar Triangles
This animated “Math Shorts” help students understand slope with similar triangles.
Please visit the PBS LearningMedia library to access the supplementary learning materials included with this video.
Common Core State Standards: CCSS.Math.Content.8.EE.B.6 (Grade 8): 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.
