Question

find equation for line perpendicular to the line y=-4x-3; containing the point 3,3 ; final answer in slope intercept form

Answer 1

anybody?

Answer 2

y=(1/4)x+9/4

Answer 3

i know the answer, its how u get there i dont

Answer 4

if slope of two perpendicular lines follow the relation.
m1*m2=-1
Use it to get slope as 1/4
write equation as y=1/4x+c
find c by putting 3,3 in equation

Answer 5

you dont neede to use point slope form?

Answer 6

if the line of the given points are perpinduclar, then the slope will be the opposite recibrical.
what you have to do next is simply use 1/4, and points 3,3 and plug it into y=mx+b
what you have is 3=1/4*3+b.
then you solve for b, which is simple algebra.
after that, you just plug it all into y=mx+b and get y=1/4x+9/4

Answer 7

can you use point slope form?

Answer 8

I think so

Answer 9

how would that work?

Answer 10

y-3=1/4(x-3)

Answer 11

i appreciate it!!

Answer 12

I really hope im right

Answer 13

you r- i got the answer key

Answer 14
