Graph y>=2x+7 y>-1/3x-2

$y \geq 2 x + 7$ $y > - \frac{1}{3} x - 2$

Step 1

Graph $y \geq 2 x + 7$ .

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 $y = m x + b$ .

$m = 2$

$b = 7$

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

Slope: $2$

y-intercept: $(0, 7)$

Slope: $2$

y-intercept: $(0, 7)$

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $2 x + 7$ .

$y \geq 2 x + 7$

Step 2

Graph $y > - \frac{1}{3} x - 2$ .

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 $\frac{1}{3}$ .

$y > - \frac{x}{3} - 2$

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

Reorder terms.

$y > - (\frac{1}{3} x) - 2$

Remove parentheses.

$y > - \frac{1}{3} x - 2$

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

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

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

$b = - 2$

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: $(0, - 2)$

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

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

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

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

Graph a dashed line, then shade the area above the boundary line since $y$ is greater than $- \frac{1}{3} x - 2$ .

$y > - \frac{1}{3} x - 2$

Step 3

Plot each graph on the same coordinate system.

$y \geq 2 x + 7$

$y > - \frac{1}{3} x - 2$

Step 4

Graph y>=2x+7 y>-1/3x-2
