A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x -3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

Which statement best describes the depth of this fish, given this equation? (7.7A)

• From a starting position of 7 meters below sea level, the fish is descending 3 meters per second

• From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second

• From a starting position of 3 meters below sea level, the fish is descending 7 meters per second

• From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second

A mathematician takes a taxi from the airport to a hotel. The taxi driver charges a $3.50 initial charge plus $2.75 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?

• y = 3.50x + 2.75

• y = 2.75(x + 3.50)

• y = 2.75x - 3.50

• y = 2.75x + 3.50
