write the equation of the line that is parallel to the line -3x-9y=4 and passes through (9,2)\r
\n" ); document.write( "\n" ); document.write( "line -3x-9y=4 \r
\n" ); document.write( "\n" ); document.write( "9Y=-3x -4\r
\n" ); document.write( "\n" ); document.write( "divide by 9\r
\n" ); document.write( "\n" ); document.write( "y= (-3/9)x -(4/9)\r
\n" ); document.write( "\n" ); document.write( "compare with
\n" ); document.write( "y= mx+b\r
\n" ); document.write( "\n" ); document.write( "slope m = (-3/9) = -1/3\r
\n" ); document.write( "\n" ); document.write( "The slope of the paralel line will be the same = (-1/3)
\n" ); document.write( "It passes through (9,2)\r
\n" ); document.write( "\n" ); document.write( "plug the cordinates to get the value of b\r
\n" ); document.write( "\n" ); document.write( "2= (-1/3)(9)+ b\r
\n" ); document.write( "\n" ); document.write( "2=-3 +b\r
\n" ); document.write( "\n" ); document.write( "b = 5\r
\n" ); document.write( "\n" ); document.write( "we know m and b\r
\n" ); document.write( "\n" ); document.write( "so the equation will be
\n" ); document.write( "y = (-1/3)x +5\r
