Step 1.1.1

Multiply $- \frac{1}{3}$ by $x$ .

$y \leq - \frac{1}{3} x + 4$

Step 1.1.2

Combine $x$ and $\frac{1}{3}$ .

$y \leq - \frac{x}{3} + 4$

Step 1.2

Reorder terms.

$y \leq - (\frac{1}{3} x) + 4$

Step 1.3

Remove parentheses.

$y \leq - \frac{1}{3} x + 4$

Step 2

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

Step 2.1

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

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

$b = 4$

Step 2.2

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: $(0, 4)$

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

y-intercept: $(0, 4)$

Step 3

Graph a solid line, then shade the area below the boundary line since $y$ is less than $- \frac{1}{3} x + 4$ .

$y \leq - \frac{1}{3} x + 4$
