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.

This video was made for the PBS LearningMedia library, thanks to a generous grant from the Corporation for Public Broadcasting. It was produced in collaboration with Utah Education Network.

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.
