Answer:
1/3
Step-by-step explanation:
Note that any line parallel to the given line will have the same slope as the line given.
Given the equation of the line expressed as x - 3y =-27
Rewrite in standard form y = mx+c where m is the slope
x - 3y =-27
-3y = -x -27
Multiply through by -11
3y = x+27
Divide through by 3
y = 1/3 x + 9
Since the slope of the line is 1/3, hence the slope of a line parallel to the line is also 1/3
