Graph y>=-1/5x-1 y<2x-6

$y \geq - \frac{1}{5} x - 1$ $y < 2 x - 6$

Step 1

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

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 $x$ and $\frac{1}{5}$ .

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

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

Reorder terms.

$y \geq - (\frac{1}{5} x) - 1$

Remove parentheses.

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

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

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

$m = - \frac{1}{5}$

$b = - 1$

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

Slope: $- \frac{1}{5}$

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

Slope: $- \frac{1}{5}$

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

Slope: $- \frac{1}{5}$

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

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

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

Step 2

Graph $y < 2 x - 6$ .

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 $y = m x + b$ .

$m = 2$

$b = - 6$

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

Slope: $2$

y-intercept: $(0, - 6)$

Slope: $2$

y-intercept: $(0, - 6)$

Graph a dashed line, then shade the area below the boundary line since $y$ is less than $2 x - 6$ .

$y < 2 x - 6$

Step 3

Plot each graph on the same coordinate system.

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

$y < 2 x - 6$

Step 4

Graph y>=-1/5x-1 y<2x-6
