graph the equation 4x+y >_ 4
\n" ); document.write( ":
\n" ); document.write( "4x + y >= 4
\n" ); document.write( ":
\n" ); document.write( "y >= -4x + 4
\n" ); document.write( ":
\n" ); document.write( "Choose some values for x and find y
\n" ); document.write( "An example x = -2:
\n" ); document.write( "y = -4(-2) + 4
\n" ); document.write( "y = + 8 + 4
\n" ); document.write( "y = 12
\n" ); document.write( ";
\n" ); document.write( "Plot the graph using following values:
\n" ); document.write( " x|y
\n" ); document.write( "-----

\n" ); document.write( " 0| 4
\n" ); document.write( "+3| -8
\n" ); document.write( ":
\n" ); document.write( "It should look like this:

\n" ); document.write( ":
\n" ); document.write( "Remember we had y >= -4x +4, which means the area of interest is at or above
