\n" ); document.write( "Constraint boundary lines:

\n" ); document.write( "\"y+=+-x%2B3\"
\n" ); document.write( "\"y+=+%281%2F2%29x%2B%281%2F2%29\"

\n" ); document.write( "Intersection point: (5/3,4/3)

\n" ); document.write( "a graph... feasibility region is above the red line and below the green line

\n" ); document.write( "\"graph%28400%2C400%2C-1%2C5%2C-1%2C5%2C-x%2B3%2C.5x%2B.5%29\"

\n" ); document.write( "The only two corners of the feasibility region are (3,0) and (5/3,4/3).

\n" ); document.write( "(3,0): P = 9(0)+3 = 3
\n" ); document.write( "(5/3,4/3): P = 9(4/3)+5/3 = 41/3

\n" ); document.write( "ANSWERS: The minimum value of P is 3, at the point (3,0).
