Answer:

C) yes, 2

Step-by-step explanation:

A direct variation means that the graph is a straight line. In this case it is:

<u>Yes, the graph is an example of direct variation.</u>

To find the constant of variation, you can use the formula:

y = \frac{k}{x}

Now, substitute the x- and y-variables for a given point:

1 = \frac{k}{2}

Finally, solve for <em>k</em>:

1 = \frac{k}{2}

k = 2

<u>The constant of variation is 2.</u>
