Graph x>=0 y<=-1/8x+5 y>=5/8x-1

$x \geq 0$ $y \leq - \frac{1}{8} x + 5$ $y \geq \frac{5}{8} x - 1$

Step 1

Graph $x \geq 0$ .

$x \geq 0$

Step 2

Graph $y \leq - \frac{1}{8} x + 5$ .

Find the slope and the y-intercept for the boundary line.

Rewrite in slope-intercept form.

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

$y = m x + b$

Simplify the right side.

Combine $x$ and $\frac{1}{8}$ .

$y \leq - \frac{x}{8} + 5$

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

Reorder terms.

$y \leq - (\frac{1}{8} x) + 5$

Remove parentheses.

$y \leq - \frac{1}{8} x + 5$

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

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

$m = - \frac{1}{8}$

$b = 5$

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

Slope: $- \frac{1}{8}$

y-intercept: $(0, 5)$

Slope: $- \frac{1}{8}$

y-intercept: $(0, 5)$

Slope: $- \frac{1}{8}$

y-intercept: $(0, 5)$

Graph a solid line, then shade the area below the boundary line since $y$ is less than $- \frac{1}{8} x + 5$ .

$y \leq - \frac{1}{8} x + 5$

Step 3

Graph $y \geq \frac{5}{8} x - 1$ .

Find the slope and the y-intercept for the boundary line.

Rewrite in slope-intercept form.

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

$y = m x + b$

Simplify the right side.

Combine $\frac{5}{8}$ and $x$ .

$y \geq \frac{5 x}{8} - 1$

Reorder terms.

$y \geq \frac{5}{8} x - 1$

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

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

$m = \frac{5}{8}$

$b = - 1$

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

Slope: $\frac{5}{8}$

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

Slope: $\frac{5}{8}$

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

Slope: $\frac{5}{8}$

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

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $\frac{5}{8} x - 1$ .

$y \geq \frac{5}{8} x - 1$

Step 4

Plot each graph on the same coordinate system.

$x \geq 0$

$y \leq - \frac{1}{8} x + 5$

$y \geq \frac{5}{8} x - 1$

Step 5

Graph x>=0 y<=-1/8x+5 y>=5/8x-1
