You can put this solution on YOUR website!
There are several ways to answer this problem.
\n" ); document.write( "You can graph it and solve it.
\n" ); document.write( "You can solve it with algebra.
\n" ); document.write( "You can plug in the choices and find the one that works.
\n" ); document.write( "plug in 2 for x and see if y is 1
\n" ); document.write( "plug in 1 for x and see if y is 2
\n" ); document.write( "plug in -1 for x and see if y is -2
\n" ); document.write( "plug in -2 for x and see if y is -1
\n" ); document.write( "One and only one of them is correct.
\n" ); document.write( "
\n" );
