You can put this solution on YOUR website!
from 1-4:
you are given a graph of the linear system of inequalities, and shaded area is a solution to that system
dashed line is not part of solution, solid line is part of solution
you are given ordered pairs and you need to look at the graph and see if given points are located in shaded area;
if they are located in shaded area, they are part of solution
if they are  located in shaded area, they are solution
1. ( , ) is located on dashed line, but it is located in shaded area; so, (,) is solution
2.( , )is located exactly on dashed line which is not part of solution, but it is located in shaded area; so, (,) is solution
3.( ,) is located exactly on solid line which  part of solution:(,) is solution
4.
( , ) is located below dashed line, but it is located in shaded area; so, (,) is solution
