The equation y = −2.5x − 5 can be used to represent this situation, where y is the depth of Dylan in meters below sea level and x is the number of seconds Dylan has been swimming. Which statement best describes the depth of Dylan, given this equation?

A. Dylan started scuba diving 2.5 meters below sea level and is ascending at a rate of 2.5 meters per second.

B. Dylan started scuba diving 5 meters below sea level and is ascending at a rate of 2.5 meters per second.

C. Dylan started scuba diving 2.5 meters below sea level and is descending at a rate of 2.5 meters per second.

D. Dylan started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.
