I am assuming I can use some of the same information from my velocity of a bullet question for this since this is also a linear equation, correct?

Water freezes at 0°C or 32°F and boils at 100°C or 212°F. There is a linear equation that expresses the number of degrees Fahrenheit (F) in terms of the number of degrees Celsius (C). Find the equation and find the Fahrenheit temperature when the Celsius temperature is 45°.
