Graph 5x-6y<=-30

$5 x - 6 y \leq - 30$

Step 1

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

Solve for $y$ .

Subtract $5 x$ from both sides of the inequality.

$- 6 y \leq - 30 - 5 x$

Divide each term in $- 6 y \leq - 30 - 5 x$ by $- 6$ and simplify.

Divide each term in $- 6 y \leq - 30 - 5 x$ by $- 6$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- 6 y}{- 6} \geq \frac{- 30}{- 6} + \frac{- 5 x}{- 6}$

Simplify the left side.

Cancel the common factor of $- 6$ .

Cancel the common factor.

$\frac{- 6 y}{- 6} \geq \frac{- 30}{- 6} + \frac{- 5 x}{- 6}$

Divide $y$ by $1$ .

$y \geq \frac{- 30}{- 6} + \frac{- 5 x}{- 6}$

Simplify the right side.

Simplify each term.

Divide $- 30$ by $- 6$ .

$y \geq 5 + \frac{- 5 x}{- 6}$

Dividing two negative values results in a positive value.

$y \geq 5 + \frac{5 x}{6}$

Rearrange terms.

$y \geq \frac{5 x}{6} + 5$

Reorder terms.

$y \geq \frac{5}{6} x + 5$

Step 2

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

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

$m = \frac{5}{6}$

$b = 5$

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

Slope: $\frac{5}{6}$

y-intercept: $(0, 5)$

Slope: $\frac{5}{6}$

y-intercept: $(0, 5)$

Step 3

Graph a solid line, then shade the area above the boundary line since $y$ is greater than $\frac{5}{6} x + 5$ .

$y \geq \frac{5}{6} x + 5$
