Determine whether the pair of lines are parallel, perpendicular, or neither

$10x-5y+2=0$ and $2y+x-6=0$

The slope of the line with the equation $10x-5y+2=0$ is $.$ The slope of the line with the equation $2y+x-6=0$ is

$($Type integers or simplified fractions.$)$

Since the slopes are the pair of lines are
