What is the slope of line perpendicular to y = 5x - 8?

Question

Accepted Answer

1. The given line is $y=5x-8$, so its slope is $m=5$.

2. A line perpendicular has slope equal to the negative reciprocal: $m_{\perp}=-1/m$.

3. Compute it: $m_{\perp}=-1/5$.

4. Therefore the correct choice is **(d) -1/5**.
