properties to model real-world situations.
1. In science class, you learned about converting temperatures between
degrees Celsius (°C) and Fahrenheit (°F), but recently you could not find a
reference with the correct formulas. You then remembered that the
relationship between °F and °C is linear.
(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

in terms of Celsius temperature; i.e. an equation of the form F = "an
