Let's first graph the line

We will put this into slope-intercept form to make this easier:

So this line looks like

Now, our graph is essentially broken up into two regions. We can take a point in each region and "test it". ((You can pick any points... because I like work to be easy... I will pick points on the x or y axis so I have a zero to deal with)
For the lower region I will use (0, 0)
so

This is not true, so we cannot shade this region.

For the upper region I will use (0,3)

This is true, so I can shade the upper region.
Since

Has a = to 10, the line will be solid.... if however it was just >, the line would be dotted as the region would get really close to the line but would never touch the line.

Hopefully this helps, let me know if you are still unsure:)
