The Answer of The following display from a graphing calculator presents the least-squares regression line for predicting the price of a certain commodity (y) from the price of a barrel of oil (x)

Write the equation of the least-squares regression line.
A) $y = 3.72 + 0.49 x$ 
B) $y = 0.49 + 3.72 x$ 
C) $y = 0.49 + 0.72009 x$ 
D) $y = 3.72 + 0.72009 x$

The Following Display from a Graphing Calculator Presents the Least-Squares y=3.72+0.49xy = 3.72 + 0.49 xy=3.72+0.49x

The Following Display from a Graphing Calculator Presents the Least-Squares $y = 3.72 + 0.49 x$
