Answer:
So our answer is

Start with the given inequality:

Set up a number line:

Now plot the point on the number line

Now pick any test point you want, I'm going to choose x=0, and test the inequality

Plug in

Since this inequality is not true, we simply shade the entire portion that does not contain the point x=0 using the point as the boundary. This means we shade everything to the right of the point like this:
Graph of with the shaded region in blue
note: at the point , there is an open circle. This means the point is excluded from the solution set.
