Question

A Girl Scout is selling cookies to raise money for her troop. She is given a certain number of cookies to sell and is tracking the number of boxes remaining each day. The table shows the relationship between the number of days she has been selling cookies and the total number of boxes remaining.

Table:
Time = x, days = y
(1, 21), (3, 17), (4, 15), (7, 9)

Which of the following graphs shows the relationship given in the table?

A: a coordinate plane with the x-axis labeled time in days and the y-axis labeled number of boxes, with a line that passes through the points (0, 27) and (2, 21)

B: a coordinate plane with the x-axis labeled time in days and the y-axis labeled number of boxes, with a line that passes through the points (0, 23) and (2, 19)

C: a coordinate plane with the x-axis labeled time in days and the y-axis labeled number of boxes, with a line that passes through the points (0, 25) and (2, 19)

D: a coordinate plane with the x-axis labeled time in days and the y-axis labeled number of boxes, with a line that passes through the points (0, 27) and (2, 23)

Answer 1

Answer: B

thats the answer the other persons right checked work

Answer 2

Answer: The answer is B

Explanation:

The answer is B because once you graph each point and draw a line through them, you will find the slope (rise/run, y/x) is -2/1 since it is a negative slope. After drawing that line, you will also find that it intersects points (0,23) and (2,19). Furthermore, you can double check this by using the slope that we found earlier. All you do is select a point already graphed and go down 2 and one to the right or go up two and one over to the left.
