Question

How do u make a perpendicular through y=4x+2 and goes through (8,-2)

Answer 1

RIGHT NOW
in you math problem

it only deals with SLOPE
so...

Answer 2

that is an example

Answer 3

slopes of perpendicular lines are negative reciprocal of each other.

Answer 4

Thanks

Answer 5

y = 4x + 2
The slope of this line is 4

The slope of the perpendicular line is -1/4

y = mx + b
y = -1/4x + b
It passes through (8, -2)
-2 = -1/4*8 + b
-2 = -2 + b
b = 0

So the perpendicular line passing through (8,-2) is:
y = -1/4x
