Respuesta :

Answer:

option D.

Step-by-step explanation:

[tex]rate \: of \: change \: = \frac{change \: in \: y}{change \: in \: x} [/tex]

let's take any point on the graph. let's say (2, 16)

and one point we know is (0, 0)

[tex]rate \: of \: change = \frac{16 - 0}{2 - 0} [/tex]

= 16($) / 2 (hrs)

= 8 $/ hrs

that is option D.

Answer:

$8/hour

Step-by-step explanation:

Hi there!

In this scenario, the independent variable is time and the dependent variable is the cost. The cost of renting the kayak depends on how much time passes. Knowing this, the answer should be formatted like _ dollars/hour, not _hours/dollar. We can rule the first two options out.

Now, looking at the graph, when 1 hour passes, the cost is $8. This occurs at point (1,8). And this is constant throughout, for example, when 2 hours pass, the cost is $16 (2,16).

Therefore, the rate of change shown in the graph is $8/hour.

I hope this helps!
