E graph shows the altitude of a helicopter over time.

DaniilM [7]

Let

x-------> the time

y-------> the altitude of a helicopter

Step 1

Find the slope of the line

we know that

the slope m of the line between two points is equal to

$m=\frac{(y2-y1)}{(x2-x1)}$

we have

$(x1,y1)=(0,10,000)\\(x2,y2)=(15,4,000)$

substitute in the formula

$m=\frac{(4,000-10,000)}{(15-0)}$

$m=\frac{(-6,000)}{(15)}$

$m=-400\frac{feet}{minute}$

therefore

the answer is the option

The slope is $-400$ . This means that the helicopter descends $400$ ft each minute.
