document.write( "They want you determine the value of the constant \"c\" in the right side of the equation.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "For it, simply substitute the given coordinates 2 for x and -3 for y into the equation\r\n" );
document.write( "\r\n" );
document.write( "    -3 - 2.5*2 = c.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then you get c = -3 - 5 = -8.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, your equation is  y - 2.5x = -8.    ANSWER\r\n" );
