Question

=12 is the function linear?

Answer 1

that is no function,
it is not even a equation

Answer 2

not even a complete expression

Answer 3

its not a complete question ...........

Answer 4

I assume typo:
y = 12 is horizontal line
x = 12 is vertical line
They are linear equations.

Answer 5

yea..............sure

Answer 6

does x=12 pass the vertical line test.
no

Answer 7

any variable with an exponent greater than 1 is not a linear equation

such as x^2 = 12 is not linear.

just look for the highest degree (aka highest exponent

Answer 8

and x = 12 technically isn't a function nor does it have slope so it isn't even a "line" by mathematical standards i guess
