Graph x+y>4 y>=3/2x-9

$x + y > 4$ $y \geq \frac{3}{2} x - 9$

Graph $x + y > 4$ .

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

Subtract $x$ from both sides of the inequality.

$y > 4 - x$

Rearrange terms.

$y > - x + 4$

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 $y = m x + b$ .

$m = - 1$

$b = 4$

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

Slope: $- 1$

y-intercept: $(0, 4)$

Slope: $- 1$

y-intercept: $(0, 4)$

Graph a dashed line, then shade the area above the boundary line since $y$ is greater than $- x + 4$ .

$y > - x + 4$

Graph $y \geq \frac{3}{2} x - 9$ .

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 $\frac{3}{2}$ and $x$ .

$y \geq \frac{3 x}{2} - 9$

Reorder terms.

$y \geq \frac{3}{2} x - 9$

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

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

$m = \frac{3}{2}$

$b = - 9$

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

Slope: $\frac{3}{2}$

y-intercept: $(0, - 9)$

Slope: $\frac{3}{2}$

y-intercept: $(0, - 9)$

Slope: $\frac{3}{2}$

y-intercept: $(0, - 9)$

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $\frac{3}{2} x - 9$ .

$y \geq \frac{3}{2} x - 9$

Plot each graph on the same coordinate system.

$x + y > 4$

$y \geq \frac{3}{2} x - 9$

Graph x+y>4 y>=3/2x-9
