The boiling point of water was measured at different locations of varying barometric pressures. A regression line of the data is y equals 1.9 x + 155.3, where y is the boiling point in degrees Fahrenheit and x is the pressure in inches of mercury.

Which statement best describes the meaning of the slope in the regression line?

A.For every 1 inch of mercury the pressure increases, the boiling point is expected to increase by 1.9 ° Fahrenheit.

B.For every 1 inch of mercury the pressure increases, the boiling point is expected to increase by 155.3 ° Fahrenheit.

C.For every 1.9 inches of mercury the pressure increases, the boiling point is expected to increase by 1.9 ° Fahrenheit.

D.For every 1.9 inches of mercury the pressure increases, the boiling point is expected to increase by 155.3 ° Fahrenheit.
