# If ‘a’ is a real number, what is the distance between the Y-axis and the line x = a?

The distance is a unit, assuming a is an arbitrary constant, which it is, given that you stated it’s a real number.

This is because the y-axis is the same as the line x = 0, and so the difference between the two lines will be a0 units, or simply a units.
