A submarine is cruising 8 meters below the surface. The captain orders a dive of another 17 meters. What is the new cruising depth of the submarine in meters?

25 meters.

Step-by-step explanation:

Given in the question that,

Initial depth of the submarine = 8 meters

After the order of the captain, the submarine was made to dive another 17 meters.

So, the final cruising depth of the submarine can be calculated by adding the initial depth of the submarine and the depth further increased upon the order of the captain.

Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
