You can put this solution on YOUR website!
intersection point is where the 2 equations are the SAME...they are equal at that point... the (x,y) of one equation is the same as the (x,y) of the other.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, we have
\n" ); document.write( "x+y = 0 and
\n" ); document.write( "2x+y = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "ignore the < and > for now...we are interested in where they ARE equal.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so sub 1 equation into the other and solve. Find the other variable afterwards.\r
\n" ); document.write( "

\n" ); document.write( "\n" ); document.write( "Sketch the graph then... look at my lessons on sketching linear equations and also anything i have on inequalities too.\r
