Answer:
Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.
Step-by-step explanation:
Jason is scuba diving at a constant rate toward the ocean floor.
Equation:
x = The number of seconds Jason has been swimming.
y=The depth of Jason in meters below sea level
General equation : y=mx+c
m = Slope = rate of change per unit
On comparing m = -2.5
Negative signs represents the descending .
So, rate of descending per second = 2.5 m/sec
-5 denotes the initial position below sea level
So, Option D is true
So, Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.
