Question

Please help! I need help with Linear Functions! I will fan and medal!!!
f(x) = -3x + 2

Linear or Nonlinear?

m =

b =

Answer 1

it is linearly because it looks like
\[f(x)=mx+b\]

Answer 2

so how do I figure out what m is and what b is?

Answer 3

\[\large f(x) = \color{blue}mx + \color{red}2 \]\[\large f(x) = \color{blue}{-3}x + \color{red}2 \]

Answer 4

so x = 5?

Answer 5

no x is a variable

Answer 6

also, i don't see any five in the question

Answer 7

lets try again

Answer 8

I'm sorry and ok

Answer 9

\[\large f(x) = \color{blue}mx + \color{red}b\]\[\large f(x) = \color{blue}{-3}x + \color{red}2\]

Answer 10

match up the colors

Answer 11

\[\huge\color{blue}m=\color{blue}{-3}\]

Answer 12

Oh I see!

Answer 13

so if m= -3 then b=2?

Answer 14

and \[\huge \color{red}b=\color{red}2\]
yes

Answer 15

I get it now! Thank you!

Answer 16

will you help me with some more?

Answer 17

f(x) = x2 - 1

Linear or Nonlinear?

m =

b =

Answer 18

I know that this one is non linear because it has an exponent

Answer 19

so how do I know what m or b is?

Answer 20

the graph is

so how can it be linear ^^

Answer 21

not linear--> no m or b
DAT SIT

Answer 22

linear equation is the one which gives straight line ~ its basic
remember
