Question

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

Answer 1

Given:

$y=\frac{1}{7}x-1$

To find:

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

Explanation:

The slope of the given line is,

$m=\frac{1}{7}$

So, the perpendicular slope will be,

$\begin{gathered} m_1=-\frac{1}{m} \\ =-\frac{1}{\frac{1}{7}} \\ =-7 \end{gathered}$

Therefore, the slope of the line is -7.

Final answer:

The slope of the line is -7.
