To solve by graphing:
1. Find two points (x,y) for each function:
-First equation:
When x=0
[tex]\begin{gathered} 0+y=2 \\ y=2 \\ \\ \text{Point: (0,2)} \end{gathered}[/tex]When y=0
[tex]\begin{gathered} x+0=2 \\ x=2 \\ \\ \text{Point: (2,0)} \end{gathered}[/tex]-Second equation:
When x=0
[tex]\begin{gathered} 0-y=4 \\ -y=4 \\ y=-4 \\ \\ \text{Point: }(0,-4) \end{gathered}[/tex]When y=0
[tex]\begin{gathered} x-0=4 \\ x=4 \\ \\ \text{Point: (4,0)} \end{gathered}[/tex]2. Use the points to graph each function: Put the points in the grind and then draw a line that passes foe each corresponding pair of points:
First function in red
Second function in blue
3. Identify the solution: The solution is the point of intersecion.
