Question

4. Is the graph an example of direct variation? If so, what is the constant of variation?

Answer 1

Answer:

C) yes, 2

Step-by-step explanation:

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

Yes, the graph is an example of direct variation.

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 k:

1 = $\frac{k}{2}$

k = 2

The constant of variation is 2.
