Question
Perpendicular lines $\ell_{1}$ and $\ell_{2}$ have slopes $m_{1}$ and $m_{2}$ respectively. Find $m_{2}$ if $m_{1}$ equals:a) 5b) $-\frac{5}{3}$c) $-\frac{1}{2}$d) $\quad \frac{a-b}{c}$
Step 1
This means that the slope $m_{2}$ of line $\ell_{2}$ is the negative reciprocal of the slope $m_{1}$ of line $\ell_{1}$. Mathematically, this can be written as $m_{2} = -\frac{1}{m_{1}}$. Show more…
