At the surface of the ocean the water pressure is the same as the air pressure above the water, 15 lb/in2. Below the surface the water pressure increases by 4.34 lb/in2 for every 10 ft of descent. Find an equation for the relationship between pressure (P, in lb/in2) and depth (d, in ft) below the ocean surface. slope
