Answer:
We do not have the image, so we can answer in a general way.
We know that the boundary line is y = -2*x – 5
We can have 4 cases:
1) a dashed line and the shaded part is above the line.
y > -2*x – 5
2) a dashed line and the shaded part is below the line
y < -2*x – 5
Here we have dashed lines because the values of the line are not solutions for the inequality.
3) a solid line and the shaded part is above the line.
y ≥ -2*x – 5
4) a solid line and the shaded part is below the line.
y ≤ -2*x – 5
Here we have solid lines because the values in the line itself are solutions.
