In this lesson, students analyze tables as a way to understand the relationship between two quantities. They identify a numerical pattern (the unit rate or constant of proportionality) in the table (MP.8) and then contextualize that value to understand what it means about the two units involved (MP.2).

Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down. And as speed goes down, travel time goes up. This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written: y = k x.A constant of proportionality is a number that relates two quantities in a proportional relationship.
