Everything looks great. Nice work. The only critique I can think is with the last section.
For something like x > 5, the dot should be an open hole. The open hole indicates "this endpoint is NOT part of the shaded region". We're visually describing any value larger than 5, so 5 is not part of the solution set.
If the inequality was x ≥ 5, then a closed filled in circle would be at the endpoint, which signals "include the endpoint".
