Answer:
The <em>x</em>, or input, is the depth.
The <em>y</em>, or output, is the water pressure.
To graph it, simply plot the depth and pressure measurements give and connect the points.
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (5, 4)
m =
=
=
