nurali · Answer

well first you must find the slope originally: 
2x=16+y 
2x-16=y 
therefore the slope is 2 
so perpendicular means put this value under 1 and take the negative of it: 
so your slope is 1/2 and then take the negative: 
-1/2 is your answer

what's the formula ? So I can try and figure it out first

if lines are perpendicular the product of the slopes is -1
m* m1 = -1
slope of line 1 = m slope of perpendicular, m1 = -1/m
