What is the slope of the line and what does it mean in this situation?
a. the slope is –2000. this means that the helicopter descends 2000 ft each minute.
b. the slope is –400. this means that the helicopter descends 400 ft each minute.
c. the slope is 400. this means that the helicopter ascends 400 ft each minute.
d. the slope is 2000. this means that the helicopter ascends 2000 ft each minute.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
