Question 1144172
Find the equation of the line using the point-slope formula. Write the final equation using the slope-intercept form. 
perpendicular to 
8y = x − 4
and passes through the point 
(−2, 1)
-------------
Do it like this one:
=====================
perpendicular to 
6y = x − 3 and passes through the point (−4,1)
----------
Find the slope of 6y = x-3
Solve for y:
y = (1/6)x - 1/2
Slope = 1/6
Slopes perpendicular are the negative inverse
m = -6
=========
Use y-y1 = m*(x-x1) where (x1,y1) is the point
y-1 = -6*(x+4) = -6x - 24
y = -6x - 23
====================================
This is basic.  It's like 2+2.
Know it.  If you don't, things will get a LOT worse.
