Sneaking Up on Slope!!!

8th Grade

Learning Targets

  • Graph proportional relationships, interpreting the unit rate as the slope of the graph.
  • Compare two different proportional relationships represented in different ways - tables, graphs, equations.
  • 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.
