Graph x-2y<=2 x+y<=0

$x - 2 y \leq 2$ $x + y \leq 0$

Step 1

Graph $x - 2 y \leq 2$ .

Write in $y = m x + b$ form.

Solve for $y$ .

Subtract $x$ from both sides of the inequality.

$- 2 y \leq 2 - x$

Divide each term in $- 2 y \leq 2 - x$ by $- 2$ and simplify.

Divide each term in $- 2 y \leq 2 - x$ by $- 2$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- 2 y}{- 2} \geq \frac{2}{- 2} + \frac{- x}{- 2}$

Simplify the left side.

Cancel the common factor of $- 2$ .

Cancel the common factor.

$\frac{- 2 y}{- 2} \geq \frac{2}{- 2} + \frac{- x}{- 2}$

Divide $y$ by $1$ .

$y \geq \frac{2}{- 2} + \frac{- x}{- 2}$

Simplify the right side.

Simplify each term.

Divide $2$ by $- 2$ .

$y \geq - 1 + \frac{- x}{- 2}$

Dividing two negative values results in a positive value.

$y \geq - 1 + \frac{x}{2}$

Rearrange terms.

$y \geq \frac{x}{2} - 1$

Reorder terms.

$y \geq \frac{1}{2} x - 1$

Use the slope-intercept form to find the slope and y-intercept.

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = \frac{1}{2}$

$b = - 1$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $\frac{1}{2}$

y-intercept: $(0, - 1)$

Slope: $\frac{1}{2}$

y-intercept: $(0, - 1)$

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $\frac{1}{2} x - 1$ .

$y \geq \frac{1}{2} x - 1$

Step 2

Graph $x + y \leq 0$ .

Subtract $x$ from both sides of the inequality.

$y \leq - x$

Use the slope-intercept form to find the slope and y-intercept.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = - 1$

$b = 0$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $- 1$

y-intercept: $(0, 0)$

Slope: $- 1$

y-intercept: $(0, 0)$

Graph a solid line, then shade the area below the boundary line since $y$ is less than $- x$ .

$y \leq - x$

Step 3

Plot each graph on the same coordinate system.

$x - 2 y \leq 2$

$x + y \leq 0$

Step 4

Graph x-2y<=2 x+y<=0
