\

The inequality is $\"\"$ .

\

Solve for y interms of x.

\

$\"\"$ (Write the inequality)

\

$\"\"$ (Add x to each side)

\

$\"\"$ (Simplify)

\

$\"\"$ (Divide each side by 2)

\

$\"\"$ (Simplify) $\"\"$

\

Draw a coordinate plane.

\

Graph the line $\"\"$ .

\

$\"\"$ means $\"\"$ or $\"\"$ .

\

So, the boundary is included in the solution set.

\

The boundary should be drawn as a solid line.

\

\

Test the point $\"\"$

\

$\"\"$ (Write the inequality)

\

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

\

$\"\"$ (Simplify)

\

The statement is true.

\

So, shade the half plane that contain $\"\"$ .
