Answer 1

To determine the constant of proportionality from the graph defined by the points (0, 0), (2, 3), and (4, 6), we first identify the ratio of \( y \) to \( x \) for the given points.

The constant of proportionality \( k \) can be found using the formula:

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

Let's calculate \( k \) for one of the points, say (2, 3):

\[
k = \frac{3}{2} = 1.5
\]

Now, let's check another point, (4, 6):

\[
k = \frac{6}{4} = \frac{3}{2}
\]

Both points give us the same constant of proportionality.

Thus, the constant of proportionality is:

\[
\frac{3}{2}
\]

So, the correct response is:

**32** \( \frac{3}{2} \)
