When you go diving, the pressure P

P per square inch (PSI) under water depends on your depth below the water surface, d

d, in feet. We find the PSI by multiplying the depth d

d by 0.434, and then adding 14.696 to the expression.

(a) What is the slope in this scenario? functions

(b) What does the slope mean?

A. It tells us how much the pressure on the diver decreases for each foot their depth increases.

B. It tells us how much the pressure on the diver increases for each unit of PSI their pressure increases.

C. It tells us how much the depth of the diver decreases for each unit of PSI their pressure decreases.

D. It tells us how much the pressure on the diver increases for each foot their depth increases.

(c) What is the y

y-intercept in this scenario? functions

(d) What is the meaning of the y

y-intercept?

A. It tells us what the pressure is when you are at the bottom of the ocean.

B. It tells us what the pressure is when you are on the surface of the water.

C. It tells us what the depth is when the pressure is zero.
