B. Graph the following systems of linear equations. Use a graphing paper. $1$ $ \begin{cases} x+y=2 \\ x+y=4 \end{cases} $ 2. $ \begin{cases} x-y=3 \\ 4x-3y=12 \end{cases} $ 3. $ \begin{cases} x=3 \\ 2x+2\bar{y} =4 \end{cases} $ 4. $ \begin{cases} 2x+y=4 \\ 4x+2y=4 \end{cases} $ 5. $ \begin{cases} y=4x+1 \\ y=-2x-5 \end{cases} $ $6$ $ \begin{cases} x+2y=7 \\ x-3y=3 \end{cases} $ C. Given the graph, categorize the kind of system of linear equations. 1. 3. 5. 7. 2. $1$ 4. 6. $8.$ D. Without graphing, identify the type of system of linear equation. – 1. $ \begin{cases} 7x-5y=12 \\ 7x-5y=1 \end{cases} $ $3. \begin{cases} 2x=8-3y \\ 2x+y=6 \end{cases} $ 5. $ \begin{cases} 4x+3=4y \\ x-5=y \end{cases} $ $2. \begin{cases} x+2y=4 \\ 2x+4y=8 \end{cases} $ $4$ $ \begin{cases} 3x-y=2 \\ 3x+y=5 \end{cases} $ 6. $ \begin{cases} 5x+2y=9 \\ 8x-3y=2 \end{cases} $
