Question 1061880: Perpendicular to y=-4x+1 passes through (-8,1)
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! Perpendicular to y=-4x+1 passes through (-8,1)
---------
Find the slope of y = -4x + 1
call it m1
(Hint: in the form y = mx + b, m is the slope)
-----
The slope of lines perpendicular is the negative inverse, = -1/mi
Call that m2.
----------
y - y1 = m2*(x - x1) where (x1,y1) is the point.
