The image shows a set of linear equation systems with a request to find their solutions graphically. Here is the breakdown of each system:

### 1. Solve the following linear systems graphically:

a)  
\[
\begin{cases} 
-x + 2y = 2 \\ 
x + y = 4 
\end{cases}
\]

b)  
\[
\begin{cases} 
a - b = 0 \\ 
-a + 2b = -1 
\end{cases}
\]

c)  
\[
\begin{cases} 
x + 4y = 6 \\ 
2x + 8y = 4 
\end{cases}
\]

d)  
\[
\begin{cases} 
2x_1 - x_2 = 4 \\ 
x_1 + x_2 = -1 
\end{cases}
\]

e)  
\[
\begin{cases} 
2x + y = 2 \\ 
4x + 2y = 4 
\end{cases}
\]

f)  
\[
\begin{cases} 
x - 2y = -4 \\ 
2x - y = 1 
\end{cases}
\]

### Approach:
To solve these systems graphically, we need to plot each pair of equations on a coordinate plane and identify the point of intersection, which represents the solution.

Let's start by solving one system (system a) graphically. We can rearrange both equations into the slope-intercept form \(y = mx + b\).

For equation (a):
1. Rearrange \( -x + 2y = 2 \) to get:  
   \( 2y = x + 2 \Rightarrow y = \frac{1}{2}x + 1 \)

2. Rearrange \( x + y = 4 \) to get:  
   \( y = -x + 4 \)

Now, plot these two lines on a graph.

Would you like me to plot the graph for system (a) and solve the other systems similarly, or would you prefer another method?
