Answer:

Option A

Step-by-step explanation:

Slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Line shown in the graph is passing through two points (2, 8000) and (4, 7000).

Therefore, slope of the given line = $\frac{8000-7000}{2-4}$

= -500 feet per mile

Which means, altitude decreases by 500 ft every mile.

(Negative sign represents the decrease)

Option A is the correct option.
