In a coordinate plane, the y-axis is a vertical line since it is perpendicular to the x-axis, the baseline. Thus, any line that is parallel to the y-axis is vertical.

This test ensures that for each input (x-value), there is only one corresponding output (y-value), satisfying the criteria of a function.<\/p>\n\n\n\n<p>If, in a <a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/geometry\/graph\">graph<\/a>, a vertical line has more than one intersection, it means that there is more than one output for a single input, which means it cannot be a function.&nbsp;<\/p>\n\n\n\n<p>Thus, any vertical line in the plane can only ever cross the graph of a function once.<\/p>\n\n\n\n<p><strong>Vertical line test examples:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"462\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/vertical-line-test-.png\" alt=\"Vertical line test\u00a0\" class=\"wp-image-41689\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/vertical-line-test-.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/04\/vertical-line-test--300x224.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"13-facts-about-vertical-lines\">Facts about Vertical Lines<\/h2>\n\n\n\n<div style=\"color:#0369a1;background-color:#e0f2fe\" class=\"wp-block-roelmagdaleno-callout-block has-text-color has-background is-layout-flex wp-container-roelmagdaleno-callout-block-is-layout-8cf370e7 wp-block-roelmagdaleno-callout-block-is-layout-flex\"><div>\n<ul class=\"wp-block-list\">\n<li>The slope of a vertical is always undefined.<\/li>\n\n\n\n<li>A vertical line always goes from top to bottom, making a 90-degree angle with the x-axis.<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"14-conclusion\">Conclusion<\/h2>\n\n\n\n<p>In this article, we learned about vertical lines, their meaning, uses, construction, properties, equation, and slope.
