Question

The distance between the line $6x+6=0$ and $x-9=0$ is

• A. $10$ units
• B. $8$ units
• C. $9$ units
• D. None of the above

Answer 1

The correct option is A $10$ units

$6x+6=0$
$x=\frac{-6}{6}=-1$

$\therefore x=-1$
$x-9=0⟹x=9$

The distance between $x=9$ and $x=-1$ is $10$ units.

So, option A is correct.
