Interpret the meaning of the slope and y-intercept in context.

Clarifications:

Essential Understandings

Concrete:

  • Match the slope to the appropriate visual (for example, given a positive slope, match the appropriate graph from a field of three: positive, negative, or no slope.)
Representation:
  • Interpret the slope as the rate of change in the data. A positive slope is data that is increasing and a negative slope is data that is decreasing.
  • Interpret the y-intercept in terms of the data.

    Example graphs illustrating positive and negative slope, undefined slope, and zero slope.

Date Adopted or Revised: 06/14 Cluster: Interpret linear models. (Algebra 1 - Major Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
