document.write( "slope 4, through the point (-2, -5)\r\n" );
document.write( "\r\n" );
document.write( "First we use the point-slope form:\r\n" );
document.write( "\r\n" );
document.write( "Point-slope formula:\r\n" );
document.write( "\r\n" );
document.write( "y - y1 = m(x - x1)\r\n" );
document.write( "\r\n" );
document.write( "where m = 4 and (x1,y1) = (-2,-5)\r\n" );
document.write( "\r\n" );
document.write( "y - (-5) = 4(x - (-2))\r\n" );
document.write( "\r\n" );
document.write( "   y + 5 = 4(x + 2)\r\n" );
document.write( "   y + 5 = 4x + 8\r\n" );
document.write( "       y = 4x + 3\r\n" );
document.write( "\r\n" );
document.write( "Now we must get it in the form ax + by = c\r\n" );
document.write( "\r\n" );
document.write( "       y = 4x + 3\r\n" );
document.write( "\r\n" );
document.write( "Add -4x to both sides\r\n" );
document.write( "\r\n" );
document.write( " -4x + y = 3\r\n" );
document.write( "\r\n" );
document.write( "But the coefficient of x must be positive to have the standard form,\r\n" );
document.write( "so we multiply through each term by -1, which changes all the signs:\r\n" );
document.write( "\r\n" );
document.write( " 4x - y = -3\r\n" );
