Video Learning Notes
Students learned that slope is the constant ratio of vertical change to horizontal change between any two points on a line, demonstrated by similar right triangles. They also connected slope to proportional relationships by graphing lines through the origin and interpreting slope as the unit rate of change.
Learning Goals
- Use similar right triangles to understand that slope, m, given as (y2 - y1)/(x2 - x1), is the same for any two points on the same line.
- Graph proportional relationships and interpret the unit rate as the slope of the line modeling the relationship.
