In looking at regression analysis further, If compared a patients physical activity vs weights in the following way

Physical activity in minutes for x	Weights in pounds for y
140	170
150	162
160	157
170	144

What would be the regression linear equation that would model this? What would be the steps to show this out? How could you use it to figure out the weight of a person who does 240 minutes of physical activity? How could you use it to find the physical activity of a 303 pound person? In a few sentences how could this be applied to your work place in another area, such as making a presentation to administration or doctors?
