Kai and Lou's Age Relationships

The video tutorial explains the concept of additive relationships using the example of Kai and Lou, where Kai is 7 years older than Lou. It demonstrates how to determine that the relationship is additive by adding 7 to Lou's age to get Kai's age. The tutorial also includes a step-by-step guide on graphing this relationship on a coordinate plane, plotting points for different ages of Lou and Kai.
