Set up a number line:
note: just replace the x with the variable you are working with
Now plot the point on the number line
Now pick any test point you want, I'm going to choose y=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 y=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 closed circle. This means the point is included from the solution set.
