1. Determine the equation of the linear (least-squares) regression line used to model this data. What is the domain of this model?

Equation: _________________________________ Domain: _________________________________

2. Interpret the slope of your regression line in the context of the problem.

3. Interpret the intercept of your regression line in the context of the problem. Does it make any sense in this problem?
