It looks like your statement is missing a word at the end. It should read: "A graph is a function if a vertical line passes through the graph at most once."
This is known as the **vertical line test**. If any vertical line intersects the graph of a relation more than once, then the relation is not a function. This is because, for a graph to represent a function, each input (or x-value) must correspond to exactly one output (or y-value).
