Question

If 'a' is is a real number,what is the distance between the Y-axis and the Line x=a? Based On Co-ordinate Geometry

Answer 1

The distance is a units, 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 a−0 units, or simply a units.

Answer 2

Step-by-step explanation:

Equation of Y-axis is x = 0. Since, ‘a’ is a real number, there are two possibilities. Case I: a > 0 Case II: a < 0 ∴ Distance between the Yaxis and the line x = a = a-0 = a Since, |a| = a, a > 0 = – a, a < 0 ∴ Distance between the Y-axis and the line x = a
