Answer:
We have to graph the solution of the linear system of equations as:
y > x
y < -x.
The graph of y>x is formed firstly we plot a dotted line of y=x and the shaded region is above the line.
whereas the graph of y < -x is formed by firstly we plot a dotted line of y=-x and then the shaded region is below the line.
The common vertex of the graph is (0,0).
The common shaded region lie in the second and third quadrant.
The graph is attached to the answer.
