Analyzing Proportional Relationship Graphs

Make Connections

Performance Task

Ways of Thinking: Make Connections

Take notes about your classmates’ explanations for how they found the constant of proportionality, formula, table, and to explain how the constant of proportionality relates to the steepness of a line.


As classmates present, ask questions such as:

  • How did you find the constant of proportionality based on that graph?
  • How did you figure out how to write the formula for that graph?
  • What is the ratio of any two points on a line with a constant of proportionality of 1?
  • How does the constant of proportionality relate to the steepness of the graph
