If a positive relationship exists between x and y,
A) an increase in x will cause y to decrease.
B) a decrease in x will cause y to increase.
C) the relationship will graph as an upsloping line.
D) the vertical intercept must be positive.

Question

Quizplus · Accepted Answer

A positive relationship means that as x increases, y also increases. This would result in an upsloping line on a graph. Choices A and B are incorrect because they suggest an inverse relationship, which is not what a positive relationship implies. Choice D is also irrelevant, as the vertical intercept can be positive or negative regardless of the relationship between x and y.
