The system of equations are $\"\"$ and $\"\"$ .

Graph:

Graph the equations $\"\"$ and $\"\"$ :

$\"\"$

Observe the graph:

The region shaded in pink color is the required solution set.

$\"\"$

Test the solution at point $\"\"$ .

Case (i):

$\"\"$ (First equation)

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Multiply)

$\"\"$ (Add)

Case (ii):

$\"\"$ (Second equation)

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Subtract)

$\"\"$ (Substitute $\"\"$ )

Therefore, the region shaded contains the point $\"\"$ .
