To solve this system of equations by graphing, we first need to graph both lines and find the point of intersection. The two equations are:

1. \( y = -2x - 4 \)
2. \( y = -\frac{1}{2}x + 2 \)

### Step 1: Graph the first equation \( y = -2x - 4 \)
This is a linear equation in slope-intercept form \( y = mx + b \), where:
- Slope \( m = -2 \)
- Y-intercept \( b = -4 \)

To plot this:
- Start at \( (0, -4) \) for the y-intercept.
- From there, move down 2 units and to the right 1 unit (since the slope is -2), giving you the next point.
- Plot a few more points if needed, and then draw the line.

### Step 2: Graph the second equation \( y = -\frac{1}{2}x + 2 \)
This is also in slope-intercept form:
- Slope \( m = -\frac{1}{2} \)
- Y-intercept \( b = 2 \)

To plot this:
- Start at \( (0, 2) \) for the y-intercept.
- From there, move down 1 unit and to the right 2 units (since the slope is \(-\frac{1}{2}\)).
- Plot a few points and draw the line.

### Step 3: Find the intersection point
Graphically, the point where the two lines intersect is the solution to the system of equations. After plotting both lines, you will see that the lines intersect at \( (2, -8) \).

### Final Answer:
The solution to the system of equations is \( x = 2 \) and \( y = -8 \), or the point \( (2, -8) \).
