Answer: See attached for the graph. Yes, it is a solution.

Explanation:

First, we will graph each of the inequalities.

y > 2x + 4

➜ We will shade above the line.

➜ The b-intercept is 4.

➜ The slope is 2.

➜ Dashed line.

-y - 2x ≥ 4

➜ The slope-intercept form of this inequality is y ≤ -2x - 4.

➜ We will shade below the line.

➜ The b-intercept is -4.

➜ The slope is -2.

➜ Solid line.

Next, we will label the solution set. I have labeled this as the instructions asked with a "S," it is where the shaded portions overlap.

Lastly, (-2, 0) is a solution. Since y ≤ -2x - 4 (-y - 2x ≥ 4) includes equal to, it is apart of the solution set.
