can a solution of a linear inequality lie on a dashed boundary line?
explain if it is or isn't.
The solution cannot lie on the dashed line. This is because the dashed boundary means that this boundary is not incorporated in the solution set. The solutions are way above or below it. Read more on http://www.wtamu.edu/academic/anns/mps/math/mathlab/beg_algebra/beg_alg_tut24_ineq.htm.
No, the DASHED line shows that solutions are above or below it...but not on it. If you think they should be solutions, ck one and you'll find that it does not make the inequality true.
