    > means dotted line also means boundary line is not a solution graph line and select a point in any region if the point is true shade that point because that is your solution region if the point is false, then that is NOT the solution region

    the whole line is dotted because the line itself is not a solution

    ok my drawing is really bad, but my line should be dotted and I tested (0,0) 4(0)+(0)>-6 0>-6 True shade side where (0,0) is located because that is the solution region Any point in that region will test True
