Answer:

<em>Answer First choice NO</em>

Step-by-step explanation:

<u>Direct Relationship</u>

Two variables x and y have a direct relationship if the function that relates them is written as:

y = kx

Where k is the constant of proportionality.

The graph of such function is a straight line passing through the origin (0,0).

The graph does not show a direct relationship because it has the shape of a curve, not a straight line.

Answer First choice NO
