Which of the following is a correct statement about slope?

Question

Quizplus · Accepted Answer

Slope is defined as the change in y divided by the change in x. For a horizontal line, the change in y is zero, so the slope is zero. For a vertical line, the change in x is zero, resulting in a denominator of zero, which is undefined, or infinitely large. Therefore, a vertical line has an infinite slope, while a horizontal line has a zero slope. Option C correctly states that a horizontal line has a zero slope, and a vertical line has an infinite slope.
