enter your answer as a ratio in simplified form in the box.
$$

the answer is 3/2

Step-by-step explanation:

hope this helps

Direct proportionality states that:

if

then;

.....[1] where, k is the constant of proportionality.

As per the statement:

The graph shown a proportional relationship.

From the graph we have;

⇒ and

Substitute these values in [1] we have;

Multiply both sides by 4 we have;

or

Therefore, the constant of proportionality is, or 3: 2
