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 />
<em>subtract 9x from both sides</em>
<em>divide both sides by 3</em>
Therefore we have the slope <em>m = -3</em>.
Put it to the equation of a line:
<em>add 3 to both sides</em>
