Answer 1

Step-by-step explanation:

A proportional relationship means that the two variables are related by a constant called constant of proportionality:

`a=kb`

k is the constant of proportionality.

To find k we have to use the values of a and b from the table:

`\begin{gathered} k=(a)/(b) \\ k=(8)/(3) \\ k=(24)/(9)=(8)/(3) \\ k=(40)/(15)=(8)/(3) \end{gathered}`

Answers:

• equation: ,a = 8/3 b

,

• constant of proportionality:, 8/3
