#### Understanding Slope with Similar Triangles

This animated “Math Shorts” help students understand slope with similar triangles.

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.
