Question: The linear model P(d) = 62.5d + 2117 is used to find the pressure (lb/ft2) at d feet below the surface of the water.
(a) What does the constant 2117 represent?
(b) What information do you get from the number 62.5?
(b) What is the pressure 200 ft below water surface?

Solution:
 
The model is given in slope intercept form y = mx + b , where m is the slope and b the y intercept.
The constant 2117, which can be viewed as the y intercept is the function value when d = 0.
This means the pressure on the surface of water = 2117 lb/ft^2.
 
The number 62.5 can be related to 'm' the slope in a linear equation. It is the rate at which the pressure is increasing for every ft below the water surface.
 
P(d) = 62.5d + 2117
P(200) = 62.5(200) + 2117 = 12,500 + 2,117 = 14,617 lb/ft^2.
