The graph of the proportional relationship y = 4x is given at the end of the question.
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
She can haul 4 bales of hay in each wagon load, hence the constant is k = 4, and the function is given by:
