Question

if a is a real number what is the distance between the y - axis and the line x=a​

Answer 1

Explanation:

Solution. 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. ... Thus, the distance between the Y-axis and the line x = a is |a| units.
