we started with
-3x> 9
First, we must solve the inequality by deciding both sides by -3. Remember, when dividing both sides of an equality by a negative number, the sign flips. now we have
x < -3
to express this in set notation, we would say “when x is an integer (written as Z), x is less than or equal to -3”, written like so:
{x c Z | x < -3}
to graph, we use a number line. Because it is equal as well, we use a closed circle.
