Answer: 1.2
Explanation:
From the table, we can observe that as the input increases by 5 units, the output increases by 6 units. therefore, the rate of change is:
(change in Output)/(change in Input)= (24-6)/(20-5)
= 18/5= 1.2
∴ This means that for every unit increase in the input, the output increases by 1.2 units
