can you help me or not??

Answer 14

Lol, what if we dont?? then?

Answer 15

then ill try yo find someone else..but I would love for you to help me

Answer 16

sooo you need negative reciprecals. Hold on I forgot how to do this

Answer 17

ok..

Answer 18

LOl, If u want me to help, i will surely! :)

Answer 19

saifoo. Help lol. I wanna know how to do this too!

Answer 20

alright, then i will do this step by stel.

Answer 21

step*

Answer 22

the slope of a perp line follow this formula:

\[\Large m_1 * m_2 = -1\]

now insert the values.. the slope for the real line is: -9/2 so.

\[\frac{-9}{2} *m_2 = -1\]
\[m_2 = \frac92\]

so here we have the slope for that.

Answer 23

the Y intercept is the same right?

Answer 24

now, insert this in y=mx +b

\[4 = \frac{9*1}{2} + b \]\[b = \frac{-1}{2}\]

so now u have the y intercpt too.

Answer 25

I guess I forgot how to use y=mx + b. I'm sensing with my powers that the 4 is from his given point, and so the 1 too must be from his given point. So you're only adding the 9/2 and + b?

Answer 26

now, just insert the slope & y-intercpt:

\[y = \frac{-9x}{2} -\frac{1}{2}\]
finally take the lcm and the cross multiply..
finally your equation will look like:

\[\Huge 2y = -9x - 1\]

Answer 27

what. How did you get -1/2 for b >.>

Answer 28

the answers are either:
a. 9x-2y=1
b.9x+2y=17
c.2x-9y=-34
d.2x+9y=38

Answer 29

i inserted the slope and the new cordinates.. to find the y-intercpt.

Answer 30

A for apple is the answer.

Answer 31

okee doke.. thanx!

Answer 32

welkx.

i never did such LONG working in my 2mnths here!

Answer 33

wait you inserted 9/2... and the coordinates 4 for y and 1 for x lol
so how did you get -1/2

Answer 34

lol, i did the working there.. u can see that.

Answer 35

I can see you multiplying through by 2 to get 8 on the left and 9 on the right, subtract to get b = 1

Answer 36

huh?

Answer 37

OH

Answer 38

4-4.5 = -1/2. this is why I fail at math

Answer 39

SAIFOO OFF THE TOP OF YOUR HEAD WHAT IS THE FOUR STEP METHOD TO INVERSE A FUNCTION????

Answer 40

LOL.

Answer 41

:3 tell meNAOW

Answer 42

sorry, where u got stuck?

Answer 43

>.> I'm working on a different question. Don't worry I got the answer right here.

Answer 44

O cool.
the last step i do is chng the y to x.

Answer 45

isn't that the first step... you change back to y at the end
