Answer:
Equation of a line passes (x1, y1) in point-slope form:
y - y1 = a(x - x1)
Slope = -2 => a = -2
=> y - y1 = -2(x - x1)
That line passes (-2, 1)
=> x1 = -2, y1 = 1
=> y - 1 = -2(x - (-2))
<=> y - 1 = -2(x + 2)

Answer:
8 minutes
Step-by-step explanation:
Step one:
given
A submarine is 105 feet below the surface of the water
depth of submarine= 105 feet
let the time of ascending be x
Required
The time taken to ascend up to 81 ft
Step two:
the expression for the situation is
<em>81=105-3x</em>
solve for x
3x=105-81
3x=24
divide both sides by 3
x= 24/3
x=8 minutes
