Final answer:
A line parallel to another with a slope of -5/6 will also have a slope of -5/6.
Step-by-step explanation:
If a line has a slope of −5/6, then a line that is parallel to this line would have the same slope. Parallel lines never intersect and have the same steepness; thus, they also have the same slope value. Hence, the correct answer is A) -5/6.
