Water is being poured into a large, cone-shaped
cistern. The volume of water, measured in cm³, is
reported at different time intervals, measured in
seconds. A regression analysis was completed and
is displayed in the computer output.

What is the equation of the least-squares regression
line?
Volume = 0.640 - 0.006(Time)
Volume = 0.640 - 0.006(Time)
Volume = -0.006 + 0.640(Time)
Volume = - 0.006 + 0.640(Time?)
