Andrea's Awesome Alligator Aquarium has a 4,400 gallon aquarium. Her turtle wanders in, and the water must be removed to get to it before the alligators do. It can be drained at a rate of 22 gallons per minute. Assuming the tank was full, and x represents the number of minutes the aquarium has been draining, which of the following equations represents the amount of water in the tank after x minutes?

• y = 4,400x + 22

• y = -22x

• y = -4,4400x - 22

• y=4,400-22x

The graph shows the descent of a skydiver with an open parachute at 1200 meters high and falling at a constant rate of 80 meters per minute.

Which statement best interprets the rate of change and the initial value in terms of the situation and its graph?

• The y-intercept or initial value represents the height of 1,200 m that the parachute opened at (starting value). The slope or rate of change represents the constant rate of 80 m per minute that the skydiver is descending.

• The y-intercept or initial value represents how fast the skydiver is falling (80m per minute). The slope is how high up the skydiver was when they opened the chute.
