Step 1.1.3.1.1

Multiply $x$ by $x$ .

$y \geq - 2 (x^{2} + x \cdot - 3 - 3 x - 3 \cdot - 3) + 2$

Step 1.1.3.1.2

Move $- 3$ to the left of $x$ .

$y \geq - 2 (x^{2} - 3 \cdot x - 3 x - 3 \cdot - 3) + 2$

Step 1.1.3.1.3

Multiply $- 3$ by $- 3$ .

$y \geq - 2 (x^{2} - 3 x - 3 x + 9) + 2$

Step 1.1.3.2

Subtract $3 x$ from $- 3 x$ .

$y \geq - 2 (x^{2} - 6 x + 9) + 2$

Step 1.1.4

Apply the distributive property.

$y \geq - 2 x^{2} - 2 (- 6 x) - 2 \cdot 9 + 2$

Step 1.1.5.1

Multiply $- 6$ by $- 2$ .

$y \geq - 2 x^{2} + 12 x - 2 \cdot 9 + 2$

Step 1.1.5.2

Multiply $- 2$ by $9$ .

$y \geq - 2 x^{2} + 12 x - 18 + 2$

Step 1.2

Add $- 18$ and $2$ .

$y \geq - 2 x^{2} + 12 x - 16$

Step 2

The equation is not linear, so a constant slope does not exist.

Not Linear

Step 3

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $- 2 x^{2} + 12 x - 16$ .

$y \geq - 2 x^{2} + 12 x - 16$
