Which graph could be used to show the situation described?
the temperature starts at 0 degrees and decreases by 12 degrees every hour.

C.

Step-by-step explanation:

We are given,

The temperature on the graph starts at 0 degrees and decreases by 12 degrees every hour.

Now, according to the options:

A. In this figure, the temperature starts from a point between ( 10,20 ) and not from 0. So, this is not correct.

B. In this figure, the temperature starts from the point 3 and not from 0. So, this is not correct.

D. In this figure, the temperature starts from 0 but it is decreasing by 1 degree every hour, which is not according to the given statement. So, this is also not correct.

C. In this figure, the temperature starts from 0 and it is decreasing appears to be decreasing by 12 degree every hour. Thus, it represents the given statement.

Hence, figure C is the correct option.
