Answer 2

great!

Answer 3

right

Answer 4

see how its repeating thats how you know

Answer 5

in the x axis

Answer 6

Which of the following equations represents a linear function?
A. y = 1/x
B. y = x^2 + 4
C. y = -2/3 x + 4/3
D. y = √ x + 1

Answer 7

How do I do that. Can you walk me through it?

Answer 8

Don't give me an answer though.

Answer 9

this 1 may be tricky

Answer 10

give me a sec

Answer 11

linear functions will not have a variable in the denominator of a fraction
will not have any exponents bigger than 1

Answer 12

@Jim766 What do you mean?

Answer 13

look at A, see how the x is in the bottom of the fraction?

Answer 14

1 bigger is a no no

Answer 15

basicly

Answer 16

that cant be linear

Answer 17

Look at B, see how it has an exponent bigger than 1, (2)
that cannot be linear

Answer 18

c can be though

Answer 19

dexter

Answer 20

A looks like this y =

Answer 21

D cannot be linear because the variable is sq rooted....we call that a sq root function.

Answer 22

I thought it was x, is it?

Answer 23

c u mean

Answer 24

and if so u are correct

Answer 25

Waoh woah woah I thought it couldn't be any of them...

Answer 26

right in your picture, x is in the bottom of the fraction...cant be linear

Answer 27

OK, that's what I thought. So NONE of them can be linear?

Answer 28

look at....C

Answer 29

no if u check c carefully you will see

Answer 30

no exponents bigger than 1
no variables in the bottom of a fraction
has got 2 variables

Answer 31

OK...what makes it linear?

Answer 32

correct good job

Answer 33

woops, i see u just put it. :) I think I see...

Answer 34

good observation

Answer 35

no exponents bigger than 1
no variables in the bottom of a fraction
has got 2 variables

if you graph it, it will make a line

Answer 36

line= linear

Answer 37

so only that is linear is c

Answer 38

if you have a graphing calculator...
if you put each in Y=
you can see their graphs

Answer 39

it basicley makes a line

Answer 40

I see. Thanks! :)
