Graph -y<=3x

$- y \leq 3 x$

Step 1

Divide each term in $- y \leq 3 x$ by $- 1$ and simplify.

Divide each term in $- y \leq 3 x$ by $- 1$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- y}{- 1} \geq \frac{3 x}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} \geq \frac{3 x}{- 1}$

Divide $y$ by $1$ .

$y \geq \frac{3 x}{- 1}$

Simplify the right side.

Move the negative one from the denominator of $\frac{3 x}{- 1}$ .

$y \geq - 1 \cdot (3 x)$

Rewrite $- 1 \cdot (3 x)$ as $- (3 x)$ .

$y \geq - (3 x)$

Multiply $3$ by $- 1$ .

$y \geq - 3 x$

Step 2

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 $y = m x + b$ .

$m = - 3$

$b = 0$

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

Slope: $- 3$

y-intercept: $(0, 0)$

Slope: $- 3$

y-intercept: $(0, 0)$

Step 3

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $- 3 x$ .

$y \geq - 3 x$
