Question

What is the slope of a lineperpendicular to the line x = 5.

Answer 1

Solution:

The equation of the line is given below as

$\begin{gathered} x=5 \\ \end{gathered}$

The line above is a vertical line

Vertical lines have an undefined slope because the horizontal change is 0 — you cannot divide a number by 0

Hence,

Since x=5 is a vertical line, the slope is undefined. The perpendicular line is horizontal and the slope is 0

Hence,

The final answer is

$\Rightarrow0$

OPTION B is the final answer
