Answer:

<h2>3x + y = b</h2>

<em>b - </em><em>any real number</em>

Step-by-step explanation:

Parallel lines have the same slope.

We have the equation of a line in the standard form <em>Ax + By = C</em>.

Convert to the slope-intercept form <em>y = mx + b</em>

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

9x+3y=-22         <em>subtract 9x from both sides</em>

3y=-9x-22         <em>divide both sides by 3</em>

y=-3x-\dfrac{22}{3}

Therefore we have the slope <em>m = -3</em>.

Put it to the equation of a line:

y=-3x+b            <em>add 3 to both sides</em>

3x+y=b
