Answer 1

Question: If 'a' is a real number, what is the distance between they is a the line x = a?

Answer:

: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 is |a|.

I Hope this Will Help you

Answer 2

Answer:

The line x=a is parallel to the Y− axis passing through (a,0)

If a>0 , then the line will be distance of a units to the right of the Y− axis .

If a<0 , then the line will be a distance of a unit to the left of the Y− axis.

Thus , the distance between the Y− axis and line x=a is ∣a∣ units
