You can put this solution on YOUR website!
Simply graph $\"y=-x%2B3\"$ and $\"y=x%2B1\"$ on one graph like this\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-5%2C+5%2C+-5%2C+5%2C+-x%2B3%2C+x%2B1%29+\"$ graph of $\"y=-x%2B3\"$ (red) and $\"y=x%2B1\"$ (green)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The solution to the system is the point of intersection. So it appears they intersect at (1,2). So the solution is (1,2).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you aren't allowed to use a graphing calculator, then you must make a table for each equation. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So if you let x=1 you get\r
\n" ); document.write( "\n" ); document.write( " $\"y=-%281%29%2B3=2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=2\"$ \r
\n" ); document.write( "\n" ); document.write( "and you would do this for every point in your table\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the table for $\"y=-x%2B3\"$ would look like\r
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "\r\n" );
document.write( "          x          y\r\n" );
document.write( "   -5.00000    8.00000\r\n" );
document.write( "   -4.00000    7.00000\r\n" );
document.write( "   -3.00000    6.00000\r\n" );
document.write( "   -2.00000    5.00000\r\n" );
document.write( "   -1.00000    4.00000\r\n" );
document.write( "    0.00000    3.00000\r\n" );
document.write( "    1.00000    2.00000\r\n" );
document.write( "    2.00000    1.00000\r\n" );
document.write( "    3.00000    0.00000\r\n" );
document.write( "    4.00000   -1.00000\r\n" );
document.write( "    5.00000   -2.00000\r\n" );
document.write( "\r\n" );
document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Also, if you're required to make tables, you would have to make another table for $\"y=x%2B1\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "After making the tables, you can simply plot them on graphing paper to see where they intersect. That intersection is the solution. \n" ); document.write( "
