A seashell is dropping at a constant rate toward the ocean floor. The equation y = -4x - 8 can be used to represent this situation,
where y is the depth of the seashell in meters below sea level
and x is the number of seconds the seashell has been dropping.
Which statement best describes the depth of the seashell, given
this equation?
A.
From a starting position of 4 meters below sea level, the
seashell is descending 8 meters per second.
B.
From a starting position of 4 meters below sea level, the
seashell is ascending 8 meters per second.
C.
From a starting position of 8 meters below sea level, the
seashell is descending 4 meters per second.
D
From a starting position of 8 meters below sea level, the
seashell is ascending 4 meters per second.
