About the Lesson

This lesson involves finding a linear equation and confirming the equation represents a proportional relationship with numeric values in ordered pairs or in functions tables.
As a result, students will:

  • Find the linear relationship given a proportional situation.
  • Find ordered pairs on the linear equation.
  • Find numeric value that fit the proportional situation.
