Question

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

Answer 1

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
