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
