slope of a line perpendicular to the given line is -1/2

Explanation:

first we find the slope of the given line

then the slope of a line perpendicular to it would be the flipped opposite of it

putting #2x - y - 8 = 0#
into slope intercept form to find the slope
we would get #y = 2x - 8#
so the given slope is #2#

then the flipped opposite of that would be #-1/2#
