Explanation:

Hello!

The vertical line test is a method to test if a graph is a function or not.

Given a graph, we can draw a vertical line anywhere on the graph. If the line intersects two or more points on the graph, it is not a function.

Reasoning

If the line passes through 2 or more points, it means that there are multiple values for the same x-value.

When you have a function, you can substitute a value for x to get a unique y-value. Having two intersections means that there are two values for one x-value.
