7 A turtle is swimming at a constant rate toward the bottom of a lake. The equation
y = -5x-2 can be used to represent this example, where y is the depth of the turtle in feet
below the surface of the lake, and x is the number of seconds the turtle has been swimming.
Which statement best describes the depth of the turtle, given this equation?
F
From a starting position of 2 meters below the surface of the lake, the turtle is descending
5 meters per second.
From a starting position of 2 meters above the surface of the lake, the turtle is descending
5 meters per second.
H
From a starting position of 5 meters below the surface of the lake, the turtle is descending
2 meters per second.
j
From a starting position of 2 meters below the surface of the lake, the turtle is ascending 5
meters per second.
