When a scientist dives in salt water to a depth of 9 feet below the surface, the pressure due to the atmosphere and surrounding water is 18.7
pounds per square inch. As the scientist descends, the pressure increases
linearly. At a depth of 14 feet, the pressure is 20.9 pounds per square
inch. If the pressure increases-at a constant rate as the scientist's depth
below the surface increases, which of the following linear models best
describes the pressure p in pounds per square inch at a depth of d feet
below the surface?
A) p= 0.44 +0.77
B) P=0.44d + 14.74
C) P= 2.2d - 1.1,
D) p = 2.2d - 9.9
