# How do you find the slope of a line parallel to 3x-y=1?

$3$

#### Explanation:

If 2 lines are parallel, it means that their slopes are same.
${y}_{1} = \textcolor{red}{m} {x}_{1} + {b}_{1}$
${y}_{2} = \textcolor{red}{m} {x}_{2} + {b}_{2}$

$\textcolor{red}{m}$ is the slope and it has to be same in each line. So in this equation, we have to convert to $y = m x + b$.
$3 x - y = 1$
$y = 3 x - 1$
As we see $\textcolor{red}{m}$ or the slope is $3$.
