Question

When underwater, the amount of pressure the water exerts depends on the depth. At a depth of 4m, the pressure is 140 kPa (kilapascals). At a depth of 9m, the pressure is 190 kPa.
a) find the equation of the line, in the form P=md+b, through the points.
^ i already found the answer, i got P=10d+100
b) what rate of change does the slope represent?
c) what is the value of the P-intercept and what does it represent?
