The constant of proportionality in the equation y = (2/3)x is 2/3.
To find the constant of proportionality in a direct variation equation, we need to look at the equation in the form y=kx, where k represents the constant of proportionality. In the given equation y=2 2/3x, we can rewrite it as y=8/3x by converting the mixed number 2 2/3 to an improper fraction.
Comparing this equation to the standard form y=kx, we can see that the constant of proportionality is k=8/3 or, in simplified form, 2 2/3.
Therefore, the correct answer is "Start Fraction 2 over 3 End Fraction".
