Explanation:
A proportional relationship means that the two variables are related by a constant called constant of proportionality:
[tex]a=kb[/tex]k is the constant of proportionality.
To find k we have to use the values of a and b from the table:
[tex]\begin{gathered} k=\frac{a}{b} \\ k=\frac{8}{3} \\ k=\frac{24}{9}=\frac{8}{3} \\ k=\frac{40}{15}=\frac{8}{3} \end{gathered}[/tex]Answers:
• equation: ,a = 8/3 b
,• constant of proportionality:, 8/3
