If ‘A’ is a Real Number, What is the Distance Between the Y-axis and the Line X = a ? - Geometry
If ‘a’ is a real number, what is the distance between the Y-axis and the line x = a ?
The line x = a is parallel to the Y-axis passing through (a, 0).
If a > 0, then the line will be a distance of a units to the right of the Y-axis.
If a < 0, then the line will be a distance of a units to the left of the Y-axis.
Thus, the distance between the Y-axis and the line x = a is |a| units.
