AIt is exactly one
BIt is undefined
CIt is exactly zero
DIt is negative
Answer & Solution
Correct answer: C. It is exactly zero
1. Slope is the change in y divided by the change in x.
2. On a horizontal line every point has the same y-coordinate, so the change in y is 0.
3. Zero divided by any non-zero change in x is 0, so the slope is zero.
