You can put this solution on YOUR website!
it looks like you saw that y changes by 4 when x changes by one\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that means that x is multiplied by 4 to get y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "but there is also a \"fudge factor\" added in (a constant term)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you look at the pairs, you can find the factor\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 4x + ? ___ 7 = 4(1) + ? ___ 11 = 4(2) + ? ___ the factor is 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the formula is ___ y = 4x + 3 \n" ); document.write( "

\n" );
