Answer:
Choice B
<h3>Step-by-step explanation:</h3><em>Please refer to my answer from this question to know more about writing a </em><em>linear</em><em> </em><em>equation</em><em> from a given scenario: </em><em><u>brainly.com/question/24599307</u></em>
Scenario: A submarine dives feet per minute.
We let , be the position of the submarine from sea level as a function of
, the time (in minutes) since the submarine dived.
The given scenario states that for every minute, the position of the submarine <u>decreases</u> (because the submarine is going in a downward direction) by feet. So
can be defined as
.
Now we can select two points for the graph. We can select points and
.
Evaluation of function:
Our points are and
Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.
So the correct graph is Choice B.
