Answer:
[tex]y=0.21x[/tex]
Step-by-step explanation:
Givens
To represent this problem as a function, we need to find the constant ratio of change, which is also called the unit rate, the number of buckets per minute, so let's divide
[tex]m=\frac{3}{14} = 0.21[/tex]
Therefore, Pip A can fill 0.21 buckets per minute.
Now, the function must be linear, where its intial condition is zero. So, the linear equation is
[tex]y=0.21x[/tex]
Which demonstrates the direct proportion between variables.
