Answer:
Marcus position: -18 meters
Step-by-step explanation:
We establish a reference system where the zero height is on the sea surface. Then all height below the sea surface is negative.
~--~---~---~---~sea--~---~---~---~---~- 0 meters ---~---~----~---~---~---~---~--

⊥ Marcus: - 18 meters
So the position of marcus is: -18 meters above sea level.
To return to the surface you must move 18 meters up.
Answer:
B
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 
m = 
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (r, - 4)
m = 
= 
, then equating gives
= ( cross- multiply )
3(r - 3) = - 12 ( divide both sides by 3 )
r - 3 = - 4 ( add 3 to both sides )
r = - 1 → B
