Answer: D. (0, -4)
=========================================================
Explanation:
If you solve for y, you would get . The less than or equal to sign shows we shade below the solid boundary line.
Of the four answer choices mentioned, only (0,-4) is in the shaded region. So this is the only solution.
If we plugged the coordinates into the inequality, we get a true statement as shown below
This is a true statement because -16 is to the left of -8 on the number line. So -16 is smaller.
In contrast, if we tried something like (x,y) = (0,-1), then we see...
Which is not true because -4 is actually larger than -8. Use a number line to see this. So (0,-1) is not a solution. The same can be said about (-2,3) and (-4,0) also.
