a business purchaseda new van for $27,500. after 5 years it's depreciated vaule is $12,000. assuming a straight line depreciation write an equation of the line giving the value V of the van in terms of the age X of the van.\r

\r\n" );
document.write( "When X = 0 years, V = $27500\r\n" );
document.write( "When X = 5 years, V = $12000\r\n" );
document.write( "\r\n" );
document.write( "So we can use the usual letters for finding equations of lines,\r\n" );
document.write( "let's use x for X and y for V:\r\n" );
document.write( "\r\n" );
document.write( "When x = 0 years, y = $27500\r\n" );
document.write( "When x = 5 years, y = $12000\r\n" );
document.write( "\r\n" );
document.write( "So the problem becomes:\r\n" );
