You can put this solution on YOUR website!
solve by graphing
\n" ); document.write( "x=-1
\n" ); document.write( "4x+y=-2
\n" ); document.write( "-----------
\n" ); document.write( "This site cannot display the graph of x=-1, which is not a function.
\n" ); document.write( "But that graph would be a vertical line containing all points where
\n" ); document.write( "x = -1.
\n" ); document.write( "----
\n" ); document.write( "Graphing 4x+y = -2 you need two points: (0,-2) and (-1/2,0)
\n" ); document.write( "Plot them and draw a line thru them.
\n" ); document.write( "-------------
\n" ); document.write( "The solution for the system of two equations is the point of intersection
\n" ); document.write( "of the vertical line and the 2nd line. That point is of the form (-1,y).
