Part A. When the temperature of the city is low the number of cups of hot chocolate sold is higher in comparison to when the temperature is higher.
Part B. Find Slope: (20,20), (60,14) --> y2 -y1 / x2 -x1 --> 14- 20 / 60 -20 = -6/ 40 = -0.15 = m
y = mx +b --> 20 = -0.15 x 20 +b ---> b = 23
y = -0.15x + 23
