Question

CAN ANYONE HELP ME???????
b=-1
(x,y)=(-3,0)
f(x)=mx+b
I have to write a rule for the linear equation .

Answer 1

So if you graph the b and the point you were given, you can find the slope. I did this and got a slope of -1/3. Then I substituted the variables. So you now have
f (-3) = -1/3 (-3) -1
Now you solve and come to get
f (-3) = 0
I'm not sure if this is what you are looking for, but this is what I did.

Answer 2

Thanks but I am trying to find the rule of the linear equation . My teacher gave me the answer which is f9x)= -1/3x-1 which is what u got but I have to show how I got that >_<

Answer 3

Okay well here is my work
f (-3) = -1/3 (-3) - 1
f (-3) = 1 - 1
f (-3) = 0

Answer 4

Thanks I have another one that im stuck on could u help me possibly?

Answer 5

Yeah i might be able to help. Let me see it

Answer 6

Okay and what do you have to do?

Answer 7

I have the answer which is the rule . it is f(x)=-2x +10 but I have to show the work on how to get that. :(

Answer 8

Okay give me a few minutes and I will see if i can get it

Answer 9

I tried it but didnt get the right answer, and I'm not sure how to do it exactly. Sorry :-\
