rewrite it so that y is on one side by itself, we get:
y >= x-2
Then you draw y = x - 2
since all points on the line are such whose y value equals the value of x-2,
and the original requirement is y is greater than or equal to x-2, the solution is the region that is about the line(represented by y=x-2)including the line
