Question 465756: Okay so I have two points and a shaded graph with nothing to plug the points into and I have to find out if the two points are solutions to the inequalities. I know that I have to look on the graph and see if the points are in the shaded region. I looked at it and one coordinate is inside the shaded region and one is out of it. Would it be considered no solution if one of the points were outside of the shaded area?
