Question

what does the slope of the line tell you about the situation?
brooke buys 120 apples.
brooke uses 1 apple for every 5 pies she bakes.
brooke uses 5 apples for every pie she bakes.
brooke has 60 apples left after she has baked 12 pies.

Explanation:

The slope in a situation involving apples and pies baked would represent the rate of apple usage per pie. If Brooke uses 5 apples for every pie she bakes, that rate (5 apples per pie) is what the slope would represent, showing the change in apples with respect to the number of pies. The other options: buying 120 apples is a total, using 1 apple for 5 pies would be a slope of 1/5 (not matching the idea of slope for apple - pie relationship here), and having 60 apples left after 12 pies is a result, not the slope's meaning.

Answer:

Brooke uses 5 apples for every pie she bakes.
