Answer:

Step-by-step explanation:

The slope is -3 and the y-intercept is -1
I think the answer might be B. $4,754.60 but I'm not sure. Sorry
Y-intercept is 25. Plug 0 in for x.
We know that
To determine the intervals you will need to find the lowest and highest numbers
lowest number------> 1
highest number-----> 35
(1 and 35).
A general rule would be 5-7 intervals,
so
I will choose 5.
Here are the intervals with the number of people that were in each:
[1-7] -----------> (9)
[8-14] ---------> (14)
[15-21] --------> (8)
[22-28] ------> (3)
[29-35]-------> (5)
The total of the frequencies was 39 people, and that is how many numbers there are.
