You can put this solution on YOUR website! are these two different questions or one?
If one problem put a solid circle on 5/3 and a solid circle on 7/3
with the line drawn between the two.
If they are two sperate questions then
solid circle on 5/3 with line drawn positive to infinity
solid circle on 7/3 with line drawn negitive to infinity
I believe the first solution is what you want though.
