Question

What would the slope of a line be if it were perpendicular to the line: y = 1 / 7x - 1 ?

Answer 1

Given:

`y=(1)/(7)x-1`

To find:

The slope of the line if it were perpendicular to the given line.

Step-by-step explanation:

The slope of the given line is,

`m=(1)/(7)`

So, the perpendicular slope will be,

`\begin{gathered} m_1=-(1)/(m) \\ =-(1)/((1)/(7)) \\ =-7 \end{gathered}`

Therefore, the slope of the line is -7.

Final answer:

The slope of the line is -7.
