Quizplus · Accepted Answer

The slope of a line is defined as the change in the y-variable divided by the change in the x-variable between any two points on the line. Therefore, the correct formula for slope is (change in y-variable divided by change in x-variable), which is equivalent to (rise over run) or (y2 - y1) / (x2 - x1). This matches the definition given in choice D, where the change in the y-variable is divided by the change in the x-variable.
