Question

The regression equation y = 1.37x +75 approximates the number of minutes it takesan employee to drive to work, y. given the number of miles the employee has todrive, X. Based on this equation, for every mile the car is driven, how much does thedriving time increase?

Answer 1

We have the equation

$y=1.37x+75$

Where y = time in minutes and x = number of miles

Then, for every mile, this is x = 1, we have:

$y=1.37(1)+75=1.37+75=76.37$

Answer: the driving time increase in 76.37 minutes
