We have to complete the table so that there is a proportional relationship between the number of apples and the weight.
The only complete row we have is 5 apples has a weight of 0.6 kg. So the constant of proportionality is:
![\begin{gathered} \text{We call k the constant of proportionality:} \\ k=(0.6)/(5)=0.12\frac{\operatorname{kg}}{apple} \end{gathered}]()
Now, we can write the equation for the relationship:
Now, we can complete the table:
![\begin{gathered} \text{For x=}2\text{ apples:} \\ y=0.12\cdot2=0.24\operatorname{kg} \\ \text{For y=}1.44\operatorname{kg}\colon \\ 1.44=0.12\cdot x\Rightarrow x=(1.44)/(0.12)=12\text{ apples} \\ For\text{ x=1 apple:} \\ y=0.12\cdot1=0.12\operatorname{kg} \end{gathered}]()
