question
henry 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 point (40, 73.5) on the line of best fit represent?
answer
when the days high temperature is 40°f, henry should expect to sell about 73.5 hot cocoas.
when the days high temperature was 40°f, henry sold 73.5 hot cocoas.
when the days high temperature was 73.5°f, henry sold 40 hot cocoas.
when the days high temperature is 73.5°f, henry should expect to sell about 40 hot cocoas.

Explanation:

In a scatter - plot with a line of best fit, the x - coordinate represents the independent variable (high temperature) and the y - coordinate represents the dependent variable (number of hot cocoas sold). The point (40, 73.5) on the line of best fit is a prediction. It means when the independent variable (high temperature) has a value of 40°F, the dependent variable (number of hot cocoas sold) is predicted to be 73.5.

Answer:

When the day's high temperature is 40°F, Henry should expect to sell about 73.5 hot cocoas.
