Answer
The slope of the line is $5$.
Work Step by Step
Parallel lines have the same slope.
Let us look at the slope for the line given.
The equation for the line given is in the slope intercept form, which is given by the formula:
$y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.
The line is parallel to $y=5x-1$, whose slope is $5$.
Thus, the slope of the line we are looking must also be $5$.
