A curve is plotted with y measured on the vertical axis and x measured on the horizontal axis. The slope of the curve equals
A) y divided by the change in x.
B) the change in y divided by x.
C) y divided by x.
D) the change in y divided by the change in x.

Question

Quizplus · Accepted Answer

The slope of a curve is defined as the change in y divided by the change in x between any two points on the curve. This is represented mathematically as (y2 - y1) / (x2 - x1), which simplifies to the change in y divided by the change in x. Therefore, the best choice is D, which is the change in y divided by the change in x.
