The slope of the line in a scatterplot that shows the relationship between price and the number of cookies sold indicates how many cookies are sold for each unit increase in price. If the slope is negative, it means that as the price increases, the number of cookies sold decreases.

Given the context provided in your question, if the slope is represented as -19.7, it would imply that for every $1.00 increase in price, the number of cookies sold decreases by 19.7.

Based on this interpretation, the correct response would be:

C For every $1.00 increase in price, the number of cookies sold decreases by 19.7.
