Graph y>=2x-8 y<-1/3x+6

$y \geq 2 x - 8$ $y < - \frac{1}{3} x + 6$

Step 1

Graph $y \geq 2 x - 8$ .

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 $y = m x + b$ .

$m = 2$

$b = - 8$

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

Slope: $2$

y-intercept: $(0, - 8)$

Slope: $2$

y-intercept: $(0, - 8)$

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $2 x - 8$ .

$y \geq 2 x - 8$

Step 2

Graph $y < - \frac{1}{3} x + 6$ .

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 $\frac{1}{3}$ .

$y < - \frac{x}{3} + 6$

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

Reorder terms.

$y < - (\frac{1}{3} x) + 6$

Remove parentheses.

$y < - \frac{1}{3} x + 6$

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

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

$m = - \frac{1}{3}$

$b = 6$

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

Slope: $- \frac{1}{3}$

y-intercept: $(0, 6)$

Slope: $- \frac{1}{3}$

y-intercept: $(0, 6)$

Slope: $- \frac{1}{3}$

y-intercept: $(0, 6)$

Graph a dashed line, then shade the area below the boundary line since $y$ is less than $- \frac{1}{3} x + 6$ .

$y < - \frac{1}{3} x + 6$

Step 3

Plot each graph on the same coordinate system.

$y \geq 2 x - 8$

$y < - \frac{1}{3} x + 6$

Step 4

Graph y>=2x-8 y<-1/3x+6
