Many of the following problems can be modeled with a linear equation. Analyze them and identify what quantities the variables x and y represent. The information provided in the problems is adequate to determine a point and a slope or two points on the line.

Temperature measured in degrees Celsius (C) is related to temperature measured in degrees Fahrenheit (F) by a linear equation. Water boils at 100°C and 212°F. Water freezes at 0°C and 32°F. Find the linear equation relating Celsius and Fahrenheit temperatures.
