Answer:
8) y > -x-3
9) One point that is a solution would be (0, 0). One point that is not a solution would be (0, -3).
Explanation:
9) We can look at the graph to the left and know that anything shaded is considered to be a solution, thus, (0, 0) would be a solution. While (0, -3) is on the line itself, the inequality only includes numbers greater (to the right) than the line, therefore anything less (to the left) than or equal to the line would not be a solution.
