Graph the following linear programming problem:

$DV$:$,x_1=$# of management science books to print, $x_2=$# of marketing books to print

MAX $60x_1+180x_2$

$ST2x_1+3x_{2}900$

$2x_1+x_{2}600$

$x_{1}250$

$x_{2}250$

$x_1,x_2,0$

Question: Which two points can be used to draw the line $2x11+x2=600?$
