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 , the pressure is approximately 500 kpa.
/1 a. state the independent and dependent variables in this
scenario.

/1 b. what is the rate of change in this relationship? c. write the equation of a linear relation representing the pressure, p, at a depth, d, under water.
