Graph the line, x%2By=-8.

Then choose a point not on the line.
Usually the origin is a good choice.
Test the inequality.
If true, shade the region containing the point.
If false, shade the region that doesn't contain the point.
(0,0)
0%2B0%3C-8
0%3C-8
False, so shade the region not containing the origin.
Since the inequality doesn't contain an equal sign, the line itself is not part of the solution region.
Hence in the graph, it's shown as a dashed line.
