a.-Slope is the ratio of the vertical change (the rise or fall) to the horizontal change (the run).
A direct relationship exists when: one variable increases and the other variable increases. An upward-sloping line or curve is used to illustrate: a direct relationship. Suppose two variables are directly related. If one variable rises, then the other variable: also rises.
A horizontal or vertical line. A line that has a different slope at each point is a: curve. In Exhibit 1A-1, as X increases along the horizontal axis, corresponding to points A-B on the line, the Y values increase.
infinite. The slope of a line parallel to the horizontal axis is: 1. Measured between two points on a curve, the ratio of the change in the variable on the vertical axis to the change in the variable on the horizontal axis is the: slope .
