Our inequation is

We can read it as the values of "x" that are greater than 0. Then 0 is not included in the solution because we want GREATER than 0, not greater or equal to.
Therefore, when we graph the solution we cannot put the full circle at zero, we must put the empty circle at zero!
And we put the line for any value greater than 0 (right side)
And so on, that's the solution of the inequation
