\n" );
document.write( "*Note: to get an 'equation' one needs to use a variable
\n" );
document.write( "1)Let x represent the number of minutes
\n" );
document.write( "At 8 pm, the temperature was 10 degrees Cel,dropping 3 degrees per minute
\n" );
document.write( "y = 10°celsius - 3*x
\n" );
document.write( "at 8:10, ten minutes will have passed
\n" );
document.write( "y = 10°celsius - 3*10min = -20°celsius\r
\n" );
document.write( "\n" );
document.write( "2)At 8 p.m., the temperature was 10 degrees Cel., and was dropping 
\n" );
document.write( "\"d degrees\" per minute
\n" );
document.write( "y = 10°celsius - d*x min 
\n" );
document.write( "7:45 is 15 min earlier
\n" );
document.write( "y = 10°celsius - d*(-15)min  = 10°celsius + 15*d \n" );
document.write( "
