Question

Brooke orders a large box of apples to make apple pies for the Fairview Food Festival. Brooke takes apples from the box to make each pie.
This situation can be modeled as a linear relationship. Use the points (4, 100) and (8, 80) to find the answer.

What does the slope of the line tell you about the situation?
A. Brooke buys 120 apples.
B. Brooke uses 1 apple for every 5 pies she bakes.
C. Brooke uses 5 apples for every pie she bakes.
D. Brooke has 60 apples left after she has baked 12 pies.

Answer 1

Slope = (80 - 100) / (8 - 4) = -20 / 4 = -5.

The negative slope means the number of apples decreases by 5 for each additional pie made, so Brooke uses 5 apples per pie. Answer: C.
