That equation does not look right. What is the \"*F\"? What are you trying to say? \r

\n" ); document.write( "\n" ); document.write( "A good relationship between Fahrenheit and Celsius can be made using the points, (F,C) for the freezing and boiling points of water. These are (32,0) and (212,100). \r

\n" ); document.write( "\n" ); document.write( "Slope is\"m=100%2F%28212-32%29=100%2F180=highlight%281%2F1.8%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From slope-intercept for for the equation of a line, \"y=mx%2Bb\", you can get formula for b, the y-intercept, as \"b=y-mx\". Pick either of the known points for this line, nomatter which, and compute b.\r

\n" ); document.write( "\n" ); document.write( "Picking (212, 100), \"b=100-%281%2F1.8%29212=highlight%28-17.8%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This then gives the equation \"C=%281%2F1.8%29F-17.8\", which you might want rearranged.
