SOLUTION: Can someone help me please? Express the interval in set-builder notation and graph the interval on a number line. [-∞,5/3] If you can not graph that is ok. Thanks

You can put this solution on YOUR website!
Express the interval in set-builder notation and graph the interval on a number line. [-∞,5/3]
-------------------------
Comment: You never have a bracket ([ or ]) where inf or -inf are involved
in the interval. The interval is always open to -inf or +inf.
[-inf, 5/3]
This should be (-inf,5/3] which is set-builder notation is {x|x <= (5/3)}
-----------------
The graph consists of a solid circle at 5/3 and an arrow extending to
the left from 5/3.
