Question

What is the slope of a line perpendicular to the line with equation y = 5x – 2?

Answer 1

Perpendicular means the negative reciprocal.
\[\LARGE x=-\frac{1}{x}\]

Answer 2

\(\bf \begin{array}{llll}
y = &{\color{red}{ 5}}x – 2\\
&\uparrow \\
&slope
\end{array}\quad negative\implies -{\color{red}{ 5}}\quad reciprocal\implies \cfrac{1}{-{\color{red}{ 5}}}\)

Answer 3

\[y=5*-1/x-2\]
