- 1. Line graphs, slope, and interpreting line graphs Charalee Pera Incorporating Technology into the Classroom Wednesday September 29 2010
- 2. Standards 9d. Students will recognize the slope of the linear graph as the constant in the relationship y = kx and apply this principle in interpreting graphs constructed from data 9g. Students will distinguish between linear and nonlinear relationships on a graph of data
