Question

Quizplus · Accepted Answer

The horizontal axis on a time-series graph represents units of time, such as years or months. It is commonly used to show how a variable changes over time. Option A is incorrect because the y-axis runs parallel to the vertical axis. Option C may confuse the horizontal axis with the change in the variable being graphed, which is actually shown on the vertical axis. Option D similarly confuses the horizontal and vertical axes, as the vertical axis is used to measure the variable being graphed.
