Find slope first
(2-1)/(8-4) = 1/4
Format: y = mx + b
y = 1/4x + b
Plug in one point
1 = 1/4(4) + b, b = 0
Solution y = 1/4x
Answer:
During cool or cold weather episodes, fuel must be consumed to make buildings comfortable living spaces. A useful indicator of fuel consumption for heating purposes is the determination of heating degree-days. They are calculated by accumulating one heating degree-day (HDD) unit for each Fahrenheit degree the daily mean (average) temperature is below the base value of 65°F (18°C). For example, a day with a maximum temperature of 60°F and a minimum of 40°F has a mean temperature of 50°F. Subtracting 50 from 65 yields 15 heating degree-day units for that day. Hence, a day with a high temperature of 45°F and a low of 25°F produces ______ HDDs.
