Yes, you can consider it a relation between the points on the x-axis, and the points on the y-axis. In fact, ANY subset of R squared (in other words, any subset of the points on a plane), including the empty set, sets that contain single points, and larger sets, can be considered a relation in R squared (i.e., two sets of real numbers).

Is a vertical line a relation?
Yes it is, but it is not a function.
What is the only type of line that is not a function?
A vertical line. Remember that one test to see if a relation is a function is the vertical line test. A vertical line would fail that of course.
Which of the following would offer proof that a relation is a function?
a vertical line
The graph of a relation must pass the vertical line test?
True
If no vertical line intersects the graph of a relation in more than one point then the relation is a function?
True.
What is a vertical symmetry in math?
a line that goes up and down
What does a straight line up and down mean in math?
Vertical
What is a mere relation?
A relation is an expression that is not a function. A function is defined as only having one domain per range, meaning that when graphed, a function will have no two points on the same vertical line. If your expression is graphed and two points do appear on the same vertical line, it is a relation, not a function.
The graph of a relation must pass the vertical line test true or false?
False
How does you know that relation is a function?
One way is to try the vertical line test on a graph!
What does a vertical line test mean in math?
Absolute value |-5| = 5
What is the math symbol for incongruency?
Three vertical lines, |, with a diagonal line across them.
