We are looking for the point out of the four listed that lies in the double hatched area on the right lower part of the graph.  (below the dotted line and above the solid line).
Be mindful of how (7,0) and (0,7) differ
Can use the 2nd Draw menu:  It can barely be seen on the x-axis but check out the graph below carefully and you will see a dot at (7,0).  See the double hatched area above!
That’s it — 2 more points 🙂
