+1982 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.
