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 $y = m x + b$ .

$m = 1$

$b = - 2$

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

Slope: $1$

y-intercept: $(0, - 2)$

Slope: $1$

y-intercept: $(0, - 2)$

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

$y \geq x - 2$

Graph $x + 2 y \geq 8$ .

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

Solve for $y$ .

Subtract $x$ from both sides of the inequality.

$2 y \geq 8 - x$

Divide each term in $2 y \geq 8 - x$ by $2$ and simplify.

Divide each term in $2 y \geq 8 - x$ by $2$ .

$\frac{2 y}{2} \geq \frac{8}{2} + \frac{- x}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} \geq \frac{8}{2} + \frac{- x}{2}$

Divide $y$ by $1$ .

$y \geq \frac{8}{2} + \frac{- x}{2}$

Simplify the right side.
