  • Use the video in a flipped classroom environment
Classroom Considerations

  • The resource mentions the cost function as a function that the class already knows
Pros

  • Video shows the relationship between the two variables using a variety of representations
  • Makes the connection between the two variables and the way individuals can graph relationships on the coordinate axis
Cons

  • Aligned standard is for only one variable equations; the video is about two-variable relationships
