Write the equation of the line with x-intercept (12, 0) and y-intercept (0, 4).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We know two points on the line, hence we can find its' gradient.\r\n" );
document.write( "\r\n" );
document.write( "gradient = (difference of y co-ordinates)/(difference of x co-ordinates)\r\n" );
document.write( "\r\n" );
document.write( "gradient = \"%284-0%29%2F%280-12%29\" = \"-1%2F3\"\r\n" );
document.write( "\r\n" );
document.write( "We know the gradient, \"-1%2F3\"\r\n" );
document.write( "\r\n" );
document.write( "Using the following formula, we can find out the equation of the line.\r\n" );
document.write( "\r\n" );
document.write( "y - example y co-ordinate = gradient x (x - example x co-ordinate)\r\n" );
document.write( "\r\n" );
document.write( "We will use (12,0)\r\n" );
document.write( "\r\n" );
document.write( "y - 0 = (-1/3) x (x-12)\r\n" );
document.write( "\r\n" );
document.write( "y = \"%2812-x%29%2F3%29\"
\n" ); document.write( "
\n" );
