\n" ); document.write( "One simple form of a linear equation specifies the starting value and the rate of change (slope):

\n" ); document.write( " $\"y+=+mx%2Bb\"$

\n" ); document.write( "The slope is m, the starting value is b.

\n" ); document.write( "The starting value is 20000.

\n" ); document.write( "The change in value is from 20000 to 2600 in 10 years. That's a change of -17400 in 10 years, a rate of -17400/10 = -1740 per year. So

\n" ); document.write( " $\"y+=+20000-1740x\"$

\n" ); document.write( "where y is the value and x is the time in years since the purchase.

\n" ); document.write( "Your post says \"select\" a linear equation, but you don't show the choices.

\n" ); document.write( "Find one which is equivalent to the one shown. \n" ); document.write( "

\n" );
