You can put this solution on YOUR website!
slope intercept form is y=mx+b
\n" ); document.write( ":
\n" ); document.write( "so we need to isolate the y term
\n" ); document.write( ":
\n" ); document.write( "first add 3y to both sides
\n" ); document.write( ":
\n" ); document.write( "3y+21=4x.........now subtract 21 from each side
\n" ); document.write( ":
\n" ); document.write( "3y=4x-21......now divide all terms by 3
\n" ); document.write( ":
\n" ); document.write( " $\"y=%284%2F3%29x-7\"$ ......there ya go ...slope is 4/3 and y intercept is -7 \n" ); document.write( "

\n" );
