it is porportional because it stays the same,  200 feet per minute

The correct answer is:

Yes, it is proportional.

Explanation:

In this relationship, we can write the equation for altitude as y = 4000-200x, where y is the altitude and x is the number of minutes.  For every minute that the plane is in the air, the altitude changes the same number of feet; this means it is a proportional relationship.
