Rate of Change
The rate of change measures how fast one variable changes in time.
In this case, we need to measure the number of soda bottles a machine can make per minute.
We can compute the rate of change by using two points (2, 56) and (7, 196).
Change of number of bottles: 196 - 56 = 140 bottles
Change in time: 7 - 2 = 5 minutes
Rate of change: 140 / 5 = 28 bottles per minute
Answer: The machine can make 28 bottles of soda each minute
