Question

part b a line is drawn to model the relationship between the number of weeks and the change in price. is the slope of this line positive or negative? why? show hints the slope is positive because the price is decreasing. the slope is negative because the price is increasing. the slope is positive because the price is increasing. the slope is negative because the price is decreasing.

Explanation:

In typical market models, as time (number of weeks) increases, if price decreases, the slope is negative; if price increases, the slope is positive. However, standard consumer behavior shows that over time, as weeks pass, prices often decrease (e.g., product depreciation, sales), leading to a negative slope. But the correct logical pairing is: a negative slope occurs when price decreases as weeks increase, and positive when price increases with weeks. The standard relationship here (price falling over time) matches the negative slope with decreasing price.

Answer:

○ The slope is negative because the price is decreasing.
