Question

Rule for a linear function?

Answer 1

How would I do that?

Answer 2

what class is this for?

Answer 3

An Algebra class, why do you ask?

Answer 4

so what is the slope of this line?

Answer 5

I ask because often people call linear the wrong thing, but in this situation it does not matter.

Answer 6

pick any two points and find the slope

Answer 7

do you want the equation for the linear function?
I am confused about the question. Rule?

Answer 8

"Write a rule for the linear function in the table"
Then the table is up there.

Answer 9

for any two points \[(x_0,y_0)and(x_1,y_1)\]the slope will be given by
\[slope=\frac{y_1-y_0}{x_1-x_0}\]
what is the slope?

Answer 10

Wouldn't it be Undefined?

Answer 11

I came up with
y = -4 x or f{x} = -4x
by trial and error.

Any one else agree?
