Step-by-step explanation:
Paralle lines have the same slope.
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have

Convert to the slope-intercept form:
<em>subtract 9 from both sides</em>
<em>divide both sides by 5</em>

Each of the answers to choose from is not the line equation sought.
The equation:
where <em>b</em> is any real number.
