When dividing or multiplying by a negative, then flip the inequality sign.
To write interval notation, use brackets
In this case, the answer is included. The answer also goes up to infinity, which will always have a parenthesis, as you cannot reach infinity:
This means that any number from
A graph would look like this:
The dot at 6 is shaded in as 6 is included in the answer.
