An airplane is flying at an altitude of 4000 feet and descends at a rate of 200 per minute. determine whether the altitude is proportional to number of minutes. explain your reasoning
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.
