To determine if the relation represented by the line is a function, we can apply the vertical line test. This test states that if a vertical line intersects the graph at more than one point, then the relation is not a function.
Since the line given in the description is upward slanting and extends infinitely in both directions without overlapping or intersecting itself, any vertical line drawn will intersect it at most once.
Therefore, the conclusion is:
**Yes, the given relation is a function.**
