Answer 2

Linear functions can always be written in the form
f(x) = mx + b
Where m (the slope) and b (the y-intercept) are real number constants
:D

Answer 3

so neither of them
?

Answer 4

?

Answer 5

13 is linear, 12 is not

Answer 6

why is 13 linear?

Answer 7

^Yeah, that
See, in number 13
m=3/2
b = -11

Answer 8

is 12 no because there is no slope variable?

Answer 9

because 13 is in the from y=mx+b where the slope is 3/2 and y intercept is -11

Answer 10

Well, there's a z in the denominator...

Answer 11

but there is a variable on the numerator in 13, is it still in mx+b form?

Answer 12

Yes...
\[\large f(x) = \frac{3}{2}x-11\]
Maybe it's clearer now?

Answer 13

yes, yes it is. as long as the varible is it he numerator i could just cast it to the side
?

Answer 14

Of course :)

Answer 15

awesome possum:)
