To find the constant of proportionality from the given points, you can use the formula for the constant of proportionality \( k \):

\[
k = \frac{y}{x}
\]

From the graph, the coordinates given are \((x, y) = \left(\frac{2}{3}, \frac{3}{4}\right)\).

Now we can calculate \( k \):

\[
k = \frac{y}{x} = \frac{\frac{3}{4}}{\frac{2}{3}} = \frac{3}{4} \times \frac{3}{2} = \frac{3 \times 3}{4 \times 2} = \frac{9}{8}
\]

Thus, the constant of proportionality is:

\[
\frac{9}{8}
\]

In simplified form, it is \( 9 \) in the numerator box and \( 8 \) in the denominator box.
