While on a trip, you notice that the video screen on the airplane, in addition to showing movies and news, records your altitude (in kilometers) above the ground. As the plane starts its descent (at time x = 0), you record the following data:Time, x (min.)Altitude, y (km)012210486684102If you were to graph these points on a graph, you would notice that the line that forms represents a linear function. What is the practical meaning of slope in this situation?

A
For every minute that passes, the airplane descends 1 kilometer.
B
For every minute that passes, the airplane ascends 1 kilometer.
C
For every 2 minutes that passes, the airplane descends 1 kilometer.
D
For every minute that passes, the airplane ascends 2 kilometers.

While on a trip, you notice that the video screen on the airplane, in addition to showing movies and news, records your altitude (in kilometers) above the ground. As the plane starts its descent (at time x = 0), you record the following data: Time, x (min.) Altitude, y (km) 0 12 2 10 4 8 6 6 8 4 10 2 If you were to graph this information, the resulting line would represent a linear function. Using this information from the table and the information on your graph, by how much does the altitude of the plane change for each three-minute change in time during the descent.

A
The altitude of the plane decreases 2 kilometers for each 3 minutes into the descent.
B
The altitude of the plane decreases 3 kilometers for each 3 minutes into the descent.
C
For every 3 minutes, the altitude of the plane increases 3 kilometers.
D
For every 3 minutes, the altitude of the plane increases 2 kilometers.
