    For a relation to be a function, each x value can be mapped to only a single y value. In a vertical line, the x-coordinate of every point is the same, so a single x-value is mapped to every real number. That is more than a single y-value, so it is not a function.

    An easy way to tell if a relation is a function from a graph is the vertical line test. Think of a vertical line moving from left to right on the graph. If in any position, the vertical line intersects more than one point of the relation, then the relation is not a function.

    All lines are functions except vertical lines.
