\n" ); document.write( "Boiling point of water 212° 100°
\n" ); document.write( "Freezing point of water 32° 0°
\n" ); document.write( "Absolute zero –459.6° –273.1°
\n" ); document.write( "1. To convert from Fahrenheit to Celsius, subtract 32 and multiply by 59 .
\n" ); document.write( "Write a formula to describe this relationship. Define any variables that you have used.
\n" ); document.write( "2. Mercury is liquid in the range from –38.20°F to 674.06°F. Use your formula to convert this range to degrees Celsius.
\n" ); document.write( "3. Rearrange the equation in a. to make Fahrenheit the subject of the formula. \r

\n" ); document.write( "\n" ); document.write( "Identify two points and create the formula.
\n" ); document.write( "Points (F,C) are (32,0) and (212,100).\r

\n" ); document.write( "\n" ); document.write( "\"C-0=%28%28100-0%29%2F%28212-32%29%29%28F-32%29\" in point-slope form\r

\n" ); document.write( "\n" ); document.write( "\"C=%285%2F9%29%28F-32%29\"\r
\n" ); document.write( "\n" ); document.write( "\"C=%285%2F9%29F-160%2F9\" slope-intercept form, which you might approximate as \"C=%285%2F9%29F-17.8\".
\n" ); document.write( "That is formula for Celsius as function of Fahrenheit.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you want F as a function of C, then just solve the equation for F.\r
