$y + 4 x > 0$

Step 1

Subtract $4 x$ from both sides of the inequality.

$y > - 4 x$

Step 2

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

Step 2.1

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

$y = m x + b$

Step 2.2

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

$m = - 4$

$b = 0$

Step 2.3

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

Slope: $- 4$

y-intercept: $(0, 0)$

Slope: $- 4$

y-intercept: $(0, 0)$

Step 3

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

$y > - 4 x$
