Question

The slope of a line is 0. What do you know about the line?

Answer 1

The answer is B. The line is horizontal. If the line was a regular diagonal slope line with a slope of 1, 2, etc., the answer would be A. If the slope was undefined, the line would be vertical. Since the slope is 0, the line doesn't increase in height or have a slope at all. It is simply a straight, horizontal line.

I hope this helps :)
