Question 1095451: a. Write a system of inequalities whose solution is represented
by the shaded region shown on the graph at the right
b. Name a point that is a solution of the system of inequalities.
c. Name a point that is not a solution to the system of
inequalities.

I figured out question 1, and I think 2
I think that question 2 is, 0,0
if someone can help me with question c, and maybe check if question B is correct than thank you very much.

Part A

The system of inequalities is

system%28y+%3E=+x-3%2C+y+%3C+expr%28-2%2F3%29x%2B3%29

-------------------

The first inequality y+%3E=+x-3 is drawn from the fact that the border line y+=+x-3 has shading above this boundary line. This is the solid line shown.

In contrast, the inequality y+%3C+expr%28-2%2F3%29x%2B3 has the boundary line y+=+expr%28-2%2F3%29x%2B3 shown by the dashed line. The shading is below this line.

-------------------

To find the equation of any line given two points, you follow this basic template:

Step 1) Find the slope using the two points. Use the slope formula.
Step 2) Find the y intercept using either y-y1 = m(x-x1) or y = mx+b

====================================

Part B

The point (0,0) is a solution to this system since it is in the shaded region. Do not forget to surround the ordered pairs values with parenthesis.

Note: Any point that is on the solid boundary line is a solution

====================================

Part C

One point that is not in the shaded region is the point (0,4). So this is one non-solution.

Note: Any points that are on the dashed boundary line (that aren't on the solid line) are non-solutions as well.
