Variables A and B are directly related. If we plot A on the horizontal axis and B on the vertical axis, the line that connects combinations of A and B plotted in a two-variable diagram would be
A)parallel to the horizontal axis.
B)downward-sloping (left to right).
C)parallel to the vertical axis.
D)upward-sloping (left to right).

Quizplus · Accepted Answer

When two variables are directly related, as one increases so does the other. This means that as A increases, B also increases, resulting in an upward-sloping line when plotted in a two-variable diagram. Therefore, the correct choice is D, upward-sloping (left to right).

Variables a and B Are Directly Related
