In water, the greater the depth, the higher the pressure.

For every 10 m increase in depth, water pressure

increases by about 100 kilopascals (kPa). At a depth of

40 m, the pressure is approximately 500 kPa.


Write the equation of a linear relation representing the pressure, p, at a depth, d, under water.
