Question

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

Answer 1

perpendicular lines have negative reciprocal slopes.
negative reciprocal of 4 is -1/4

input (8,-2) -->(x,y)
and slope -> m --> -1/4
into

y = mx + b
solve for b
then put b and m back into your equation to get the slope-intercept form.

Answer 2

So what is b?
