The slope of a line parallel to the line x + 5y = 9 is; Choice B: -1/5
Slope of a line
The slope of parallel lines from line geometry are equal.
The given parallel line equation is; x + 5y = 9:
Hence, it follows that the two lines have equal slopes.
By rewriting the equation to take the slope-intercept form of straight lines, it follows that;
