You can put this solution on YOUR website!
the solution will be where the two lines intersect
\n" ); document.write( "the standard form for a line is y = mx + b where m is slope and b is y intercept
\n" ); document.write( "put both equations in standard form
\n" ); document.write( "we begin with
\n" ); document.write( "-3x-y = 7
\n" ); document.write( "2x + 3y = -7
\n" ); document.write( "1) -y = 3x +7
\n" ); document.write( "y = -3x -7
\n" ); document.write( "2) 3y = -2x -7
\n" ); document.write( "y = -2x/3 -7/3
\n" ); document.write( "now our two equations are
\n" ); document.write( "y = -3x -7
\n" ); document.write( "y = -2x/3 -7/3
\n" ); document.write( "graph of the equations is
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+-3x+-7%2C+-2x%2F3+-7%2F3%29+\"
\n" ); document.write( "the two lines intersect at point (-2, -1)\r
