"Sketch the graph the feasible region"
x+y is greater than or equal to 7
----------------------
x+y >= 7
Solve for "y":
y >= -x + 7
--------------
Graph the equality, y = -x + 7:
If x = 0, y = 7
If x = 1, y = 6
Plot the two points, (0,7) and (1,6) and draw a line thru them:
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C-x%2B7%29
-----------------------
Since you also want the points where y is greater than -x+7,
shade the half-plane above the equality line.
-----------------------
The line and the half-plane make up the graph you want.
