HELP @Godlovesme write an equation in slope-intercept form of a line that passes through the given point and is perpendicular to the graph of the given equation. (-4,3); y=1/4x-4 Write an equation for the perpendicular line in slope intercept form.
r u familiar with the point-slope form
just kidding it is: y2-y1=m(x2-x1)
@Godlovesme

sorry my internet was slow =0 u r right @kyley_bear do u know what y1, x1, and m stands for?
I know that m is slope. but dont know what x1 and y1 are.
Its okay my internet always gets super slow when i get on openstudy.
x1 is ur given x-coordinate when y is ur y in this case we r given (-4,3)
perpendicular lines have negative reciprocal slopes frist
as @AlexandervonHumboldt2 said perpendicular lines have actually opposite and reciprocal slope we r given 1/4 so the perpendicular will be -4 confused @kyley_bear
.... a little i get what y1 and x1 are but what does the negative reciprocal thing have to do with this. it is just consfusing me..

|dw:1419980446800:dw| those are perpendicular lines cuz one is increasing(+ve slope) if u look closely while the other is decreasing(-ve slope) can u c that
ohhh okay so the lines making the perpendicular line are pointing in a negative and a positive direction.

yes @kyley_bear since we have slope of -4 and an ordered pair pf (-4,3) can u set up an equation
@kyley_bear u there?
yeah my comp is messing up sorry
its okay i understand
im back @kyley_bear
@Godlovesme I had to leave to lol I am back. this is like phone tag xD
lol :)
okay so what do i need to do?
use the point-slope formula we have slope = -4 y1--> 3 and x1 --> -4 y-y1= m(x-x1) y-3=-4(x- - 4) can u solve from there? :)
