If 1982 is the base year, and it's the year x=0, then 2 points on your line are:
\n" ); document.write( "(0,10385)+(30,23872) so:
\n" ); document.write( "y=449.57x+10385
\n" ); document.write( "Tuition in 2030:
\n" ); document.write( "y=10385+449.57(48)
\n" ); document.write( "Slope indicates rate of growth in tuition per year. ☺☺☺☺
\n" ); document.write( " \n" ); document.write( "
\n" );
