While speaking on the phone to a friend in Oslo, Norway, you learned that the current temperature there was -23 Celsius (-23°C). After the phone conversation, you wanted
to convert this temperature to Fahrenheit degrees, °F, but you could not find a
reference with the correct formulas. You then remembered that the relationship
between °F and °C is linear. [UW]
a. Using this and the knowledge that 32°F = 0°C and 212°F = 100°C, find an
equation that computes Celsius temperature in terms of Fahrenheit; i. e. an
equation of the form C = “an expression involving only the variable F.”
