Question

christopher has a part - time job at an ice skating rink selling hot cocoa. he decided to plot the number of hot cocoas he sold relative to the days high temperature and then draw the line of best fit. what does the slope of the line represent? answer the average change in the number of hot cocoas sold for every additional degree of the days high temperature. the rate of change in the days high temperature for every additional hot cocoa sold. a prediction of number of hot cocoas sold when the temperature is 1°f. a prediction of the temperature when 1 hot cocoa is sold. submit answer

Explanation:

The slope of a line in a linear - regression context (line of best fit) represents the rate of change of the dependent variable (number of hot cocoas sold) with respect to the independent variable (day's high temperature). For every one - unit increase in the independent variable (one additional degree of the day's high temperature), the slope gives the average change in the dependent variable (number of hot cocoas sold).

Answer:

The average change in the number of hot cocoas sold for every additional degree of the day's high temperature.
