Step-by-step explanation:

Step 1: Let's evaluate the inequality y ≥ 1/2x -2.

First, since the symbol ≥ is used the extremes are included. So, it has to be a continuous line.

If you obserse the point of the line y = 1/2x - 2:

x = 0; y = 1/2*0 - 2 = -2

(0, -2)

And

x = 2; y = 1/2*2 - 2 = 1 - 2 = -1

(2, -1)

You can observe that it is the line that is "more horizontal".

Since it asked for y-values equal or greater to 1/2x -2, the part at the top of the line must be highlighted.

So, you have options A and C.

Step 2: Let's evaluate the inequality y > -2x - 4

First, since the symbol > is used the extremes are not included. So, it has to be a dropped line.

Second, since y-values greater than -2x - 4 are required, the right part has to be highlighted.

Observing the graphs,

The answer is C.
