The boiling point of water, T (measured in degrees), at altitude a (measured in feet) is modeled by the function                           T(a) = -0.0018a + 212. In terms of altitude and temperature, which statement describes the meaning of the slope?

• The boiling point increases by 18 degrees as the altitude increases by 1000 feet.
• The boiling point increases by 1.8 degrees as the altitude increases by 1000 feet.
• The boiling point decreases by 8 degrees as the altitude increases by 1000 feet.
• The boiling point decreases by 1.8 degrees as the altitude increases by 1000 feet.
