(b)Write the equation of theleast-squares regressionline for your data. Then on thescatter plotfor your data, graph this regression equation by plotting two points and then drawing the line through them. Round each coordinate to three decimal places.

Regression equation:

Amount of hot chocolate sold (in liters)

y 2 4 6 8 10 12 14 16 18 20 22 24 x 3 6 9 12 15 18 21 24 27 30 33 36 0

High temperature (in

)

(c)Use your regression equation to predict the amount of hot chocolate sold on a day with a high temperature of

.Round your answer to the nearest whole number.
