Answer 1

yes

Answer 2

As a diver swims deeper underwater, the water pressure in pounds per square inch (PSI) increases on the diver. The table below shows the pressure in PSI for several depths of water.

Which equation represents p as a function of d?

Answer 3

p = 4.3d
p = 0.43d
p = 23.3d
p = 2.33d

Answer 4

This function is a linear function, therefore look at the chart. Every time the depth goes up 10 feet, the PSI increases by a factor of 4.3, so answer is if depth is x and the PSI is x it is y = 0.43x, or the second answer from the ones you named.

Example from chart: 10 feet 4.3 PSI
20 feet 8.6 PSI
30 feet 12.9 PSI
Attached is the full work behind this linear problem like any other linear problem.

Thank you so much!
