I'm having a hard time with graphing this problem. Could someone please help?
Graphing has never been one of my strongest points.
Graph the system of inequalities.
x+3y is less than or equal to 9, 3x+y is less than or equal to 9, x is greater than or equal to 0, y is greater than or equal to 0.
I thought that I had the graph but it turned out to be wrong.
Thanks.

    first expression
    below the line through (9,0) and (0,3)
    below the line through (3,0) and (0,9)
    Those happen to intersect at (4.5,4.5)
    above the x axis and to the right of the y axis
