The equation that represent a proportional relationship is:


y=kx

If cruise ship move 49.5 feet for every gallon that mean:


\begin{gathered} y=kx \\ y=49.5x \end{gathered}

Where y define a distance that cruise ships move and x fuel in gallon 49.5

is a proportionality constant.

Previousaly it moved 36 feet per gallon that mean:


\begin{gathered} y=kx \\ y=36x \end{gathered}

Proportionality is 36 is define as value of y in unit value of x.
